PerkinElmer, in conjunction with the U.S. EPA, originally developedan analyzer and methodology tocollect and measure C₂-C₁₂ hydro-carbons automatically, in the field,without the use of liquid cryogen.This established method, which has been successfully employed for many years with PerkinElmer Ozone Precursor Analyzers, now includes fully integrated technologies incorporating PPC in both the Clarus GC and TurboMatrix Thermal Desorber (TD) components of the system.

The custom integration The UNITY-xr Air Server allows continuous, unattended and cryogen-free monitoring at low to sub-ppb levels and automatic sequencing between a minimum of 3 channels (sample, standard & blank). Markes Series 2 TD systems offer splitless desorption & uniquely high cryogen-free retention volumes for ultra-volatiles such as acetylene & ethane. Systems are operated in remote, unattended monitoring stations, with data accessed via telemetry and processed/validated at remote network control centres.

The Merlin MicroScience Dilution System (MMDS) is a gas blending system and a major enhancement to the automated VOC analyzer. It includes hardware to generate humidified air utilizing air from the existing air purifier and compressor which is required for the precursor system. This humidified air is used to generate daily system blanks and the calibration standard blend for introduction into the TD system. Calibration samples are generated by dilution of static span gases of 30 ppbv to 1 ppmv concentrations with humidified air using a micro gas blender. This dilution system is capable of blend ratios of as much as 1:10,000. It is a low volume blend apparatus with a clearing time of less than five minutes and all wetted parts are constructed of stainless steel.
