uiBomcD. me.GC-4500 Gas Chromatography System 5 kinds of sample injectors and all conventional detectors can be attachable depending on samples for analysis. In particular, for analysis of environmental samples (water quality, air, soil and wastes) satisfactory outcome can be achieved by connecting a sample preparation system such as the Purge & Trap. Features: • Automatic flow control and ignition of the FID- flame • Auto-start of chromatogram when sample is injected • Gas save function (Capillary Injector) • TCD maximum current control based on the type of gas • Optional valves (solenoid, 2-position) control function • Automatic notification of power-off Auto Sampler/Injector: • Dual inlet injection capability • Variable injection/syringe fill rates • Methods linking • Multiple solvenl/waste bottles • Syringe range 5uL-250uL • Air gapping capability • Multiple tray options: 120 vials, 1,8mL; 220 vials, 0.8mL; 60 vials, 10mL Gas Sampling Valve: • Two Valves can be controlled by Air Actuation • Full automation system is built along with the automatic Run/Stop function INLET SYSTEM - Excellent accuracy, reproducibility Packed Inlet: • 1/4", 1/8" Glass-lined Metal Liner are available • On-Column injection method (direct injection of sample into column) is available using 1/4" Glass Column • 0.53mm ID Capillary Column can be used Capillary Inlet: • High resolution, prompt analysis time and most typical inlet system • Split and Splitless mode can be selectable Labomed, Inc., Mailing Address: 2728 S La Cienega Blvd., Los Angeles, CA 90034 U.S.A.

If you are looking for a sampling system to replace an older, less reliable auto sampler, the GC-4500 Liquid Auto Sampler is the logical choice. The flexibility of the...

uiBomcD. me.GC-4500 Gas Chromatography System GC-4500 HEADSPACE AUTO SAMPLER Patented Dual Needle Dynamic Headspace The GC-4500 Headspace Auto Sampler utilizes a closed sample introduction system. Unlike syringe injection systems, the loss of headspace vapor during the injection process due to vapor pressure changes is never a concern. In addition to the sensitivity benefits of the Dynamic Headspace technology, the GC-4500 Headspace Auto Sampler delivers the added flexibility of performing traditional fixed loop injections and time-based injections incorporated within a single system....
