Chromacol, based in Hertfordshire, UK, produces a range of vials, caps and seals suitable for use in environmental sampling and analysis.
Its vials include EPA vials that meet the requirements of sampling for volatile organic hydrocarbons.
Certification is included with Class 300 products showing levels of VOA below 5ppb for named components, and its products are available in 20ml and 40ml volumes with injection caps fitted with clean PTFE-lined silicone rubber septa.
New additions to the company's range are TOC vials certified to less than either 10ppb or 20ppb of total organic carbon. For analysis of potable water with low allowable organic levels, these vials give assurance of minimum interference and effective calibration of systems.
