Environmental laboratories have demanding customers that require samples be run efficiently and at a reasonable price. To help laboratories increase their efficiency and keep per sample costs low, ASAP Analytical developed the TITAN XL and the TITAN PCU. The Titan XL large volume PTV inlet and Titan PCU Peltier Cooling Device allow the user to inject sample volumes into the GC greater than 5 ul. The increase in injection volume is directly related to an increase in sensitivity and concentration of the sample. The injection of a larger volume of sample means less time spent collecting, preparing and shipping samples — this increased efficiency results in a rapid ROI for the TITAN XL and PCU hardware.
The Titan XL inlet contains a programmable heater that can reach sub-ambient or sub-zero temperatures using the stand-alone Titan PCU. In the past, the temperature was maintained at these reduced setpoints using LN2 or CO2. The addition of the TITAN PCU, you can remove LN2 dewars and CO2 tanks from the area directly around the GC. The Titan PCU is compact and maintenance free. After injecting the sample into a cool inlet, ballistic heating allows the sample to be rapidly vaporized and introduced to the capillary column. The highly concentrated sample is then analyzed like a standard injection amount.
The Titan XL inlet with the PCU cooling device can save an environmental laboratory on the cost of solvents, inbound shipping, containers, and cryogenic gases. With the smaller sample size, solvent consumption can be significantly reduced. The smaller sample size will also eliminate the need for large 1L containers. Replacing these larger containers with 100 ml or 40ml vails will reduce shipping cost. The addition of the TITAN PCU can eliminate the need for LN2 or CO2 further lowering the cost of ownership.
Examples of applications that can benefit from this technology include 3511/8270 PAH, 3511/8270 PAH SIM, DRO/ORO, 35100/8015, and Pesticides/PCB.
