Seal Removal Tool, Spare Parts.T-9, Seal Removal Tool Calion standards are premixed and adsorbed into a solid phase. These standards are ideal for in field use because they contain no liquids. Calion PV Mixes are used for Torion T-9 calibration, including both mass and GC retention time calibrations. The combination of Custodion SPME sampling with Calion standards provides robust and rapid capability for in-field calibration because they contain no liquids.
