SEARCH: About company news Research and development Manufacturing complex Quality control laboratory ABOUT THE COMPANY // QUALITY CONTROL LABORATORY Quality Control Laboratories (QCL) of the "ASTOR" company provides analytical control of product quality in accordance with the requirements for the content of impurity compounds for high-purity gases for the electronics industry ("electronic gases"), as well as for gases - refrigerants. The quality control carried out is multi-level and is carried out at all stages of processing: from the acceptance of raw materials to the final quality control of the final product. The available equipment and the methods and methods of analysis used can be successfully applied in other fields of technology: from monitoring the state of the environment to researching new materials for microelectronics. Analytical equipment used in LCC. Elemental analysis: IRIS Advantage (USA) - Inductively Coupled Plasma (ICP) atomic emission spectrometer. Designed for quantitative determination of micro amounts of chemical elements in gases, liquids and solids. The accuracy of the method is ensured by the ability to determine several lines in the spectrum for each element. Detection limits for some elements (in aqueous solutions) Identification of new impurities. Gas chromatograph HP6890 Plus with mass selective detector HP5973N with extensive library of mass spectra for mass selective detector (NIST98 MS Library Bundle). This device allows one to obtain a mass spectrum of both the main substance and any of its micro impurities up to a concentration of 1 ppm, and the substance is identified by the mass spectrum with a probability of coincidence up to 99%. Chromatographic determination of impurities. Gas chromatograph UNICAM ProGC with a highly sensitive detector for ionization due to a pulsed electric discharge in helium (The pulsed discharge ionization detector (PDID)). It is used to determine trace amounts of air components, organic halogen derivatives, hydrocarbons with a lower detection limit of up to 0.05 ppmv. Gas chromatograph SHIMADZU 14BPTF with two detectors operating simultaneously: flame ionization detector (FID) and thermal conductivity detector (TCD). It is used to determine trace amounts of air components, organic halogen derivatives, hydrocarbons with a lower limit of determination up to ppmv units. Determination of moisture (determination of low concentrations of water) and acidity. Moisture Analyzer AMETEK Model 5800 Moisture Analyzer: Range of determined water concentrations: 0.1 - 100 ppmv. Moisture analyzer MEECO Aquamatic +: Range of determined water concentrations: 0.035 - 20 ppmv Waters HPLC liquid (ionic) chromatograph. It is used to determine the trace amounts of anions after contact of the electron gas with water (control of possible decomposition processes, hydrolysis of electronic gases, the presence of acid-forming impurities).
