COMO ARMAR SU PROPIO DISENO DE CROMATOGRAFO

1. Pick a chassis. What is your application? If you will be injecting by gas sampling valve, purge & trap, thermal desorber, or any other injector types in addition to on-column, then choose our versatile Model 8610C, which can mount up to five different injectors simultaneously.

For dual oven applications or two GCs in one, choose the 8610D chassis.

you will be injecting by syringe only, you can choose the ultra-compact Model 310.

For industrial rack systems, choose our Model 410 rackmount chassis.

f you want to add detectors to an existing GC, choose the Model 110

For any model GC chassis except the 110, a single channel PeakSimple data system is standard equipment. If you'll be ordering more than one detector on your GC, you will need a four or six channel data system. The one and four channel data systems connect to your Windows™ computer's serial port, and the six channel model connects to the USB port.

 

2. Choose your detectors. Detector types are selected depending on the particular measurement application , the required detection limit, matrix interferences, and/or regulatory guidelines. Since all five of our chassis can mount up to four detectors simultaneously (some can mount five or even six), you can perform a surprising variety of applications with one instrument.

3. Choose your injectors. Injector types are selected by the user depending on the particular measurement application, detection limit, and regulatory requirements. Each GC chassis except the 110 comes standard with an On-Column injector. The Heated Flash Vaporization, Heated Split/Splitless, and PTV injectors are upgrades to the standard On-Column injector. There are 17 injector types from which to choose. Up to five injectors may be mounted simultaneously on Models 8610C and 8610D. The Model 310 will accommodate a single On-Column, Heated Flash Vaporization, Heated Split/Splitless, or PTV injector. Rack-mountable Model 410 can accommodate a gas sampling valve and a single On-Column, Heated Flash Vaporization, Heated Split/Splitless, or PTV injector.

Sample Types and Appropriate Injectors
LIQUIDS: On-Column, Heated Flash Vaporization, Heated Split/Splitless, PTV, Heated Static Headspace, Purge & Trap, Liquid Injection Valve, Liquid Autosamplers, or Headspace Autosampler

SOLIDS: Thermal Desorber, Heated Static Headspace, PTV, Method 5035 Purge & Trap, or Headspace Autosampler

GASES: On-Column, Gas Sampling Valve, Method TO-14 Air Concentrator, or Heated Static Headspace

SPME FIBERS: Heated Flash Vaporization with Low Volume SPME Liner, or Heated Split/Splitless

4. Accessorize.

We have Gas Line Installation Kits for any type of gasrequired for SRI GC systems operation.

Our built-in, "whisper quiet" Air Compressor can supply air carrier or detector makeup gas.

The H2-50XRXR hydrogen generator supplies up to 50mL/minute at 30psi.

The Methanizer accessory allows FID detection of CO and CO2 down to the ppm range.

Although multiple injectors and detectors can be built into an SRI GC chassis, there are instances where certain components would occupy the same space, or we simply run out of room. If you are not sure if everything you want will fit, call one of our knowledgeable technical support agents for help. We may be able to make your dream system, but there will be an additional custom configuration charge.
