Helium ionization gas chromatograph GC-6600 is a gas chromatograph with high sensitivity helium ion detector for gas trace impurity analysis, suitable for hydrogen, oxygen, argon, nitrogen, helium, neon, krypton, xenon, carbon dioxide Analysis of impurities in gases, etc.
The original imported helium ionization detector and automatic switching valve are used to establish a complete analysis process, and a single injection can complete the separation and detection of conventional impurities. The dead volume that may occur in the entire analysis process is controlled to the smallest possible size, thereby eliminating the interference of residual gas on the analysis and improving the authenticity of the detection.Details descriptionHelium ionization gas chromatograph GC-6600 is a gas chromatograph with high sensitivity helium ion detector for gas trace impurity analysis, suitable for hydrogen, oxygen, argon, nitrogen, helium, neon, krypton, xenon, carbon dioxide Analysis of impurities in gases, etc.The original imported helium ionization detector and automatic switching valve are used to establish a complete analysis process, and a single injection can complete the separation and detection of conventional impurities. The dead volume that may occur in the entire analysis process is controlled to the minimum, thereby eliminating the interference of residual gas on the analysis and improving the authenticity of the detection.The self-developed valve-column integrated heating device can reduce the connection pipeline between the valve and the column, reduce the dead volume, increase the sensitivity and reduce the purging time, and the detection limit can reach ppb level.The most advanced pressure-sensing automatic sampling system has a higher degree of automation. It can simplify the sampling operation process and reduce the sampling error of personnel.Reference standardGB/T3634.2-2011 "Pure hydrogen, high purity hydrogen and ultrapure hydrogen" GB/T 14599-2008 "Pure oxygen, high purity oxygen and ultrapure oxygen"GB/T 8979-2008 "Pure nitrogen, high-purity nitrogen and ultra-pure nitrogen" GB/T 4842-2006 "Argon"GB/T 4844-2011 "Pure Helium, High-Purity Helium and Ultra-Pure Helium" GB/T 17873-1999 "Pure Neon"GB/T 5829-2006 "Krypton" GB/T 5828-2006 "Xenon"HG/T 3633-1999 "Pure Methane" GB 10621-2006 "Food Additives" liquid carbon dioxideGB/T 23938-2009 "High Purity Carbon Dioxide" GB/T 28125.1-2011 "Determination of Hazardous Substances in Air Separation Process"GB/T 16942-2009 "Gas for Electronic Industry" Hydrogen" GB/T 16943-2009 "Gas for Electronic Industry" helium"GB/T 16944-2009 "Gas for electronic industry Nitrogen" GB/T 16945-2009 "Gas for Electronic Industry ArgonGB/T 14604-2009 "Gas for electronic industry Oxygen" GB/T 14600-2009 "Gas for Electronic Industry" Argon Oxide Nitrogen"GB/T 14601-2009 "Gas for electronic industry Ammonia" GB/T 24469-2009 "Gas 5N Hydrogen Chloride for Electronic Industry "GB/T 18994-2003 "Gas for Electronic Industry" High Purity Chlorine"GB/T 14851-93 "Gas for electronic industry Phosphine" GB/T 17874-1999 "Gas for Electronic Industry Boron TrichlorideGB/T 15909-2009 "Gas for electronic industry Silane" GB/T 21287-2007 "Gas for Electronic Industry" Nitrogen trifluorideGB/T18867-2014 "Gas for Electronic Industry" Sulfur HexafluorideGB/T 28726-2012 "Gas Analysis Helium ionization gas chromatography"Detection type and detection limit :Detection limit (ppb) of PDHID for some impurities |

Instrument Features1. Main features1.1 New type of networked control and transmission to realize real-time monitoring and data collection by multiple people:It adopts the advanced 10/100M adaptive Ethernet communication interface and built-in IP protocol stack to set the IP address of the instrument, so that the instrument can realize long-distance control of the chromatograph and spectrum acquisition and data transmission through the intranet and the Internet. . The instrument is designed with 3 independent connection processes, which can be connected to the local place through the Internet It is convenient for multiple people to monitor the operation of the instrument in real time and analyze the data results, and improve work collaboration and immediacy.1.2 The networked chromatography workstation realizes that one computer can monitor N gas chromatographs at the same timeThe NETChrom TM workstation equipped with the GC-6600 instrument can support multiple chromatographs to realize data processing and reverse control at the same time, reaching the industry level, effectively solving the problem of too many laboratory computers and freeing up the experimental space. The analysis parameters of the sulfur hexafluoride analyzer, including the setting or display of carrier gas pressure, sample pressure, temperature, etc., are all performed through the workstation, which is easy to operate and can grasp the analysis conditions in real time.1.3 Highly sensitive helium ionization detector (PDHID)The system is equipped with a helium ionization detector (PDHID), which has a high linear response to conventional impurities such as H2, O2, N2, CH4, CO, CO2, etc. This detector is a highly sensitive general-purpose detector with high response to almost all inorganic and organic compounds. It is especially suitable for the analysis of high-purity gases. It can detect up to ng/g (ppb) level detector. The newly formulated national standards for most gas products stipulate that helium ionization detectors are used to replace the original thermal conductivity detectors, which greatly improves the analysis capabilities of gas products.1.4 Adopt center cutting technology to realize a high degree of automation of the instrument: Using the purging type automatic ten-way valve produced by VICI company to complete the center cutting and backflushing technology, with the purging type automatic six-way valve, the separation, selection and detection of complex samples can be completed in one injection. The samples are effectively separated through chromatographic columns with different conditions, and the process of sampling, cutting, column selection and backflushing of the purge valve is automatically controlled by the time program set by the workstation.1.5 Multi-column systemThe system is equipped with multiple independent oven temperature control units, using one main oven and multiple auxiliary ovens to independently control the temperature of different chromatographic columns. Different chromatographic columns are used to separate samples in different ovens and activate them separately, avoiding the problem of disassembling and assembling chromatographic columns during testing and maintenance.1.6 Helium Purifier:HP-2 type helium purifier is a special carrier gas purifier produced by VICI company. Its purification matrix is a non-volatile adsorbent alloy. There is an oxide film on the surface of the adsorbent particles that needs to be activated by heating. The activation process It must be done in a vacuum or inert gas environment, which allows free diffusion of helium gas, prevents the formation of an oxygen purification layer, and allows the adsorption of impurity gases. HP's sorbent material has good thermal stability, including two temperature control ranges. 1.7 Pressure reducing valve and sampling valve without dead volume to prevent analysis interference caused by gas residue:The carrier gas pressure reducing valve adopts an all-stainless steel carrier gas pressure reducing valve with two-stage pressure stabilization function, which greatly improves the pressure stability, ensures the stability of the baseline, and also reduces the dead volume in the valve body.The sample sampling adopts the sampling valve without dead volume and the sampling method with purging protection, which effectively avoids the problem of air residue and reduces the impact of the sampling process on the analysis to the lowest level.1.8 Digital electronic zero adjustment technology to enhance the anti-interference ability of the instrument:The detector signal zero adjustment adopts electronic zero adjustment technology, uses high-precision digital circuit for base current compensation, realizes the electronic adjustment of output signal level, reduces parasitic parameters, and thus has strong anti-interference ability.1.9 Automatic gas cut-off protection function to ensure the safe operation of the detectorIt has an intelligent gas cut-off protection function. When the carrier gas pressure is lower than the safety threshold, the system will automatically cut off the detector voltage, and the chromatograph will automatically cool down to protect the detector and the chromatographic column from damage.2.
