Shanghai Korea chamber instrumentation agent import customs clearance company Shanghai Korea chamber instrumentation agent import customs clearance company taking into account various factors, a city in the EPA group of experts chose the instrument imported domestic GCMS think the market is not long, but in some key parameters There are a wide gap with imported products. At the same time, the Group also believes that the current domestic commercialization recently launched by inductively coupled plasma mass spectrometry products, its technical performance immature technology, no mature application cases. Recently, Leshan City Environmental Protection Bureau intends to purchase GC-MS, inductively coupled plasma mass spectrometry, 8 sets of instruments. In order to meet its environmental quality and safety testing requirements, this procurement instrument intended for the purchase of imported products. Wherein upon proof GC-MS, the Group believes that "domestic GC-MS market launch time is not long, but in some of the key parameters and imported products have a larger gap." The reasoning inductively coupled plasma mass spectrometry with Miriam, the Expert Group also believes that "the current domestic product has just launched the commercialization of its technical performance immature, mature application no case." All the expert advice reasoning is as follows: First, the GC expert appraisal opinion: This product is mainly used water samples, soil organic matter in the air kind of testing, according to "Environmental surface water testing standards", "indoor air quality standards" and other national and industry standards as well as strengthen our region's environmental quality supervision and management requirements, must have reliable quality and advanced technology The detection limit of the analytical instruments low mass range of domestic temperament can do:. 1.5-1000 amu; 2, import GC-MS maximum scan rate, and made maximum scan rate can do 10000 Da / sec; 3, Imported GC-MS sensitivity: EI full scan to detect 1 pg OFN, SNR can be achieved greater than 800: 1 RMS, while the domestic GC-MS sensitivity: EI full scan to detect 1 pg OFN, the signal to noise can do more than 30: 1 RMS. Therefore, the Group agreed that the introduction of the domestic market, GC-MS is not long, but in some of the key parameters and there is a wide gap between the imported products. At the same time, the product does not belong to the "Chinese ban on imports, restrictions on imports of products catalog" national ban on imports and restrictions on imported products, the proposed purchase of imported products. Second, the headspace autosampler expert appraisal opinion: 1, to be imported products for water, environment, food testing, require the use of high sensitivity instrumentation, test results are accurate, efficient, domestic instrument performance are still gaps in terms of accuracy and quality. 2, for my unit higher technical requirements for equipment, domestic products can not meet the technical requirements. Such as: imported automatic headspace sampler using pressure injection technology can balance the conventional static headspace which guarantees a narrow peak shape, improve the detection sensitivity, reproducibility and accuracy, while the domestic ethanol Determination Headspace simply can not do, I will not be able to meet the requests for accuracy. 3. The product does not belong to the "China Import & catalog" banned or restricted products. Current domestic automatic headspace sampler Although technically made progress than before, while the instrument's accuracy, stability, and other aspects of the detection limit and there is a gap of imported equipment, domestic products can not meet work requirements. Third, purge and trap concentrator expert opinion argument: According "Surface Water Quality Standard test methods" organics testing standards in the use of gas chromatography mass spectrometry to detect drinking water systems often requires the use of surface water samples were concentrated into the purge and trap sample method for the analysis of halogenated hydrocarbons and other volatile organic compounds in water. Automatic purge and trap system is concentrated injection gas chromatography - mass spectrometry injections supporting device into the kind of stability and reproducibility of the data determined by gas chromatography analysis of the stability and reproducibility of test results in order to guarantee accurate sex, reproducibility, and ease of operation. Need to reach their targets: super performance capture, have advanced mass flow controllers to ensure the accuracy of the transmission gas pipeline to ensure that the minimum requirements for the use of inert residues. Learned through market research, purge and trap device current domestic production, not only in the autosampler design deficiencies, and there is no precise flow control system. In order to better serve the masses to provide security in the environment of surface water is more accurate, more scientific basis. Proposed purchase of imported products. Fourth, portable turbidity expert appraisal opinion: According to the actual situation of the procurement unit, Resolution: Accuracy: reading, attention: the calibration mode: choose two, three or four-point calibration, measurement methods: nephelometry assay, in line with ISO7027, and the import of portable turbidity measuring turbidity, suspended solids can be detected simultaneously, with two sets of light source and silicon photo detector. The technical specifications of these domestic products can not be achieved at the same time, the product does not belong to the state to restrict imports of products, it is recommended to buy imported portable turbidity meter. Five, emergency detection boxes expert opinion argument: according to actual usage procurement unit, the device is able to complete the requirements under various field conditions of the field testing, the instrument needs to include: dual-chamber incubator, incubator 12-volt rechargeable battery, hand pressure-vacuum filtration pump, related equipment, carrying case, and all items related auxiliary; supplies and accessories are placed in a box provided; dual-chamber incubator: a two independently temperature controlled chamber and the temperature and time controller can be carried out simultaneously cultured fecal coliform and total coliform, support for external AC power supply or by a 12-volt rechargeable battery; manual pump - can be carried out on-site rapid vacuum filtration of water samples, complete microbial sample collection; arsenic analyzer - based on arsenic principle plaque assay, detection can be completed within 20 minutes, with a tail gas absorber without operator in a fume hood; turbidity meter - operator requirements, with a 4-point calibration function. Technical indicators than domestic products can not be achieved at the same time, the product does not belong to the state to restrict imports of products, it is recommended to buy imported emergency detection box. Six, Portable Dissolved Oxygen Meter expert appraisal opinion: expert opinion argument, based on the actual usage of the procurement unit: Requires that the device supports automatic salinity and barometric pressure compensation, dissolved oxygen concentration and saturation support multi-mode calibration domestic products can not meet operational needs . Recommend purchasing imported products. Seven, inductively coupled plasma mass spectrometer is determined that the device uses mainly for water samples and food samples of all the elements in the periodic table, and according to "Surface Water Environmental Quality Standard", "groundwater environmental quality standards," which Measurement of antimony, barium, beryllium, boron, molybdenum, cobalt, nickel, vanadium, thallium, titanium and other elements need to purchase. Currently just launched commercial products appeared, its technical performance immature, no mature application cases. The detection limit of the resolution is only low resolution, can not be online adjustable. Can not meet the operational needs of the purchaser. Compared with similar products in foreign countries, domestic equipment; resolution online adjustable, can be set up in a single analysis of the different elements of different resolutions. The use of units to meet environmental quality and safety testing requirements. The product does not belong to the state to restrict imports of products, it is recommended to buy imported products. Shanghai Korea chamber instrumentation agent import customs clearance company Shanghai Korea chamber instrumentation agent import customs clearance company used the old machine import customs clearance company | used old machine import customs agents | provide quality import customs clearance services | professional old machine equipment import customs clearance company | Old How machine record | How old machine seized abroad | foreign countries which were what can be done overseas shipment inspection and quarantine agency, called the inspection / how clearance, see below for you to speak analysis. Record: old second-hand machines, used equipment imported Chinese port clearance, according to the State Administration of Commodity Inspection and the General Administration of Customs on import of the relevant provisions of the old machine, used old equipment imported into the country must be filed in the old electromechanical final shipping address, From the results of the old electromechanical filing abroad to confirm whether or not to do pre-shipment inspection and quarantine, it must be noted that, for the record all to do before the goods to Hong Kong, otherwise there will be, after the arrival of the goods need to do know that pre-shipment inspection quarantine and can not do the embarrassment, the record time (Information furnished complete 10-15 days). Seized: foreign pre-shipment inspection and quarantine, we called in the inspection industry term, mainly on the mechanical age, performance and other aspects of testing, in general we are all seized goods sent to Hong Kong, conducted by the designated agency in Hong Kong Detection can also be detected in a foreign country, appointed by the Hong Kong people to go abroad in the inspection agency, as appropriate cost and time will be longer, lower operational flexibility. So on the old mechanical and electrical inspection we recommend have done in Hong Kong, we have a special warehouse can store the goods in Hong Kong. Import clearance: After filing the inspection done, the transport of goods from Hong Kong to Shanghai (domestic ports), they begin to declare the work, the application process, the most experienced of the most troublesome thing is nothing more than the customs at trial and at trial a series of required information, including the original manufacturer fp sometimes simply can not provide, because some devices are already used for many years, and manufacturers are likely to shut down and perhaps collapse, so the original manufacturers to provide new machines fp sometimes impossible to achieve Therefore, this proposal when all the old electromechanical declared fair and reasonable price reporting, time and cost otherwise encountered at trial delay of more harm than good. Finished goods will have a tax clearance inspection, inspection of goods is nothing more than look at the old and new reporting meets the truth, whether the content of the nameplate declare the truth, there is no cargo other things, such as entrainment. Cargo port clearance after delivery to the final receipt, and the last one is the final part of factory inspection, contact the teacher to see if the goods inspection and record the contents of the same.
