The JAS UNIS inlet is designed for special high temperature applications like SimDis or H53. The special design with its low thermal mass is based on the UNIS 2100 PTV injector and can reach a maximum temperature of 500 °C. The UNIS 3100 HT PTV provides both split/splitless and PTV modes. JAS Provide several solutions for the analysis of Boiling Point Distribution (SIMDIS) for Crude oil, Lube Oil and residuals in one system. With the Agilent Gas Chromatograph and Stainless Steel capillary columns, it is possible to combine low temperature SIMDIS with the high Temperature SIMDIS.
