The fused silica lined, metal heated transfer line operates at 200\u003csup\u003e°\u003c\/sup\u003eC, hot enough for most applications. However, analysis of high boiling analytes may not be possible if they could condense in the line at this temperature.

An optional, \"whisper quiet\" air compressor may be installed to provide air for FID, DELCD, and\/or FPD detectors. The standard Model 110 is equipped with analog signal cable output (0-5V) for connection to your data system, integrator, or strip chart recorder.

Our solution is to use an inert transfer line leading to a splitter, and a 60-meter thick film capillary column. While Teflon columns are sometimes also used for sulfur analysis, the natural gas analysis (using molecular sieve and HayeSep D) requires column temperatures of 250°C or higher.

The CCD is maintained in an oxidative environment by using air carrier gas. When a hydrogen or hydrocarbon molecule impacts the hot bead, it combusts on the surface and raises the temperature and resistance of the platinum wire. This resistance change causes the detector output signal to change, thus producing a peak.

The TCD can detect concentrations from 100% down to around 100 ppm on a flat baseline with sharp peaks. Where the peak is broad or the baseline is not flat, detection limits of 300 ppm are more realistic. For lower detection limits, the HID detector may be more suitable for inorganics, and the FID detector provides 1ppm detection for hydrocarbon species.\u003c\/p\u003e\n\u003cp\u003eThe TCD consists of four tungsten-rhenium filaments in a Wheatstone bridge configuration.  Electric current flows through the filaments, causing them to heat up. Carrier gas (usually helium, which has very high thermal conductivity) flows across the filaments, removing heat at a constant rate. Two of the filaments are exposed only to carrier gas (reference), and two are exposed to the carrier\/sample flow. When a sample molecule with lower thermal conductivity than the carrier gas exits the column and flows across the two sample filaments, the temperature of the filaments increases. This temperature increase unbalances the Wheatstone bridge and generates a peak as sample molecules transit through the detector.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eA filament protection circuit prevents filament damage by disabling the current if carrier pressure is not detected by the GC, but cannot prevent filament damage in all circumstances.

interferences which would complicate an ECD analysis (such as ambient oxygen). Sample preparation which might be required for ECD work is not required for the DELCD because of its total selectivity to chlorine and bromine, and because the FID pre-combusts any contaminants. In the high sensitivity mode (hydrogen off, using dry cylinder air), the DELCD can detect down to the low picogram range. In this mode, the DELCD is about 100 times more sensitive than when used with the FID in low sensitivity mode.\u003c\/p\u003e\n\u003cp\u003eThe DELCD measures the ClO2 present in the FID exhaust gas. Because the FID combusts the sample upstream of the DELCD, all hydrocarbons are converted to CO2 prior to the DELCD, thereby preventing large hydrocarbon peaks from contaminating the DELCD. Since the DELCD operates at close to 1000°C, it can tolerate the water-saturated FID effluent and measure the chlorine and bromine content simultaneously with the FID hydrocarbon content measurement. This is especially useful for measuring chlorinated VOCs under a solvent peak, or measuring PCB peaks obscured under large amounts of diesel fuel. This detector combination is often used with our Thermal Desorber and Purge \u0026amp; Trap, which concentrate the sample to achieve lower detection limits.

When electro-negative compounds enter the cell, they immediately combine with some of the electrons, temporarily reducing the number remaining in the electron cloud. The detector electronics, which maintain a constant current (about 1 nanoampere) through the electron cloud, are forced to pulse at a faster rate to compensate for the decreased number of free electrons.

On today's Buck GCs, the oven wall is much thinner. This allows the syringe needle to penetrate well inside the column oven, thus depositing the sample into the bore of the column itself.
