SAM GC-600 Chemical Hazards Monitor – for More Safety in the WorkplaceAmazing where you can goOperating principleThe SAM GC-600 Chemical Hazards Monitor is a high-performance analyzer that is based on GC techno-logy. It was developed specifically for continuous chemical hazards monitoring and is used where highly toxic or carcinogenic substances may be present in plant air or in the workplace. Based on its high level of selectivity and sensitivity, as well as its low detection and alarm limits, the SAM GC-600 is a reliable, robust monitor for hazardous substance exposures in the ppb to ppt range. It not only offers the reliabi-lity you need, it can also help you to continuously improve your production processes.Operating principleThe heart of the SAM GC-600 Chemical Hazards Monitor is a gas chromatograph equipped with an accumulation module (A). The air that is to be analyzed is continuously drawn in at all sampling points by means of two pumps (P) and – depending on the measuring path selected – passes through a multiposition valve (V) and the adsorbent-containing accumulation module. Here, all substances not normally found in air are first adsorbed, then thermally desorbed, separated from each other chro-matographically, and then detected (D). Finally, the software (PC) calculates the substance concentrations from the chroma-tograms and manages all the functions of the SAM GC-600. This controller is based on a PC, running under the Windows® operating system. The software, which was especially developed for this unit, allows all measurement results to be managed, archived, and evaluated statistically, and it also allows the alarm thresholds to be set. It provides high system functionality, robust operation, and can be individually configured. In addition, digital and analog outputs permit communication with process control systems as well as remote maintenance.SAM GC-600 Chemical Hazards MonitorVPN2PDA PC31 Operating principle Highly toxic substances Software controller display12324 5 Accumulation module Multiposition valve45Applications, PerformanceApplicationsDimethyl sulfate and diethyl sulfateDespite their toxicity, these two substances are widely used as alkylation agents. However, they can be reliably detected well below existing limit values using the SAM GC-600 Chemical Hazards Monitor. The low detection limit (<1 ppb) permits an early response before any serious threat to human health. Bis(chloromethyl)ether (BCME)This highly toxic substance is formed spontaneously when formaldehyde is used in the presence of hydrogen chloride (chloro-methylation reactions). BCME’s workplace limit of just 1 ppb is a clear indicator of how extremely dangerous it is. Thanks to its ability to reliably detect concentrations as low as 10 ppt, the SAM GC-600 keeps you on the safe side.• Early alarm triggering signaling exposure to hazardous substances – warning and display already well below existing limits thanks to adjustable alarm thresholds• Highly selective and interference-free measurement – no false alarms * To date, analysis methods have been developed for more than 50 substances (see separate list of substances).Outstanding performance – your benefitand no resulting interruptions in operations• Individual customized method development in the laboratory plus implementation and optimization on site – development of special so-lutions for reliable chemical hazards monitoring*• Wide bandwidth – nearly all substances having a boiling point <250 °C or a vapor pressure >0.000001 mbar can be analyzedSolvias Chemical Hazards Monitoring – Precise, Specific, for More Safety1 2 Alarm status Chromatogram dimethyl sulfate (40 ppb)12SpecificationsPower consumption 2.3 kVAPower supply 230 V/ACWeight approx. 70 kg20–80 % RH, non-condensing Dimensions 850 mm x 850 mm x 1500 mmAmbient temperature 10–35 °C/50–95 °FHumidityOptions• Detectors: FID, ECD, FPD• Sample loop or accumulation module• Stream selector for 9 or 15 channels• Various standard GC columns and adsorbentsSolvias AGRömerpark 24303 KaiseraugstSwitzerlandTel. +41 61 845 60 00Fax +41 61 845 69 00www.solvias.cominfo@solvias.comSAM GC-600 Chemical Hazards Monitor
