TC-20 & TC-20 TAG

Conditioning and dry-purging units for multiple sorbent tubes

TC-20™ and TC-20 TAG™ are compact, stand-alone devices for the simultaneous conditioning or dry-purging of up to 20 thermal desorption sorbent tubes. TC-20 is used by thermal desorption–GC analysts who want to improve their laboratory’s productivity by avoiding using valuable instrument time for conditioning sorbent tubes. TC-20 TAG is a variant of the TC-20 for those who use Markes’ RFID TubeTAG tube tagging system with single-bed sorbent tubes. It is especially useful for those working to the US EPA Method 325 regulation.

MTS-32 (multiple-tube sampler)

The MTS-32 Multi-tube sequential sampler is a compact, robust, and portable sampler, designed for unattended sampling of air onto a series of sorbent tubes. Ambient air is pulled sequentially through a series of up to 32 industry-standard thermal desorption tubes by a low-flow sampling pump. Each tube is sampled at the same flow rate, so that the same volume of air is collected.

- Field-portable – the MTS-32 can be used virtually anywhere

- Labour-saving, unattended sampling – retrieve the instrument at the end of the extended sampling period

- Trusted sample integrity – tubes are sealed with diffusion-locking technology, preventing unwanted air ingress and sample loss

Micro-Chamber/Thermal Extractor

The Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a versatile and compact unit with four small cylindrical chambers that enables the sampling of chemicals released from products or materials. Released volatile and semi-volatile organic compounds (VOCs and SVOCs) are collected onto sorbent tubes for analysis by TD–GC–MS. Applications range from emissions screening of construction materials, consumer products, and car trim to aroma or fragrance profiling.

- Designed for sampling VOCs or SVOCs emitted from products and materials.

- Humidifier and permeation accessories extend the capabilities of the instrument.

- A full range of accessories for the Micro-Chamber/Thermal Extractor is available.

Kori-xr

Cryogen-free water management module for online and canister samples

Kori-xr™ is a module that efficiently removes humidity from canister or on-line samples acquired using Markes International’s UNITY-xr systems, without affecting analyte recovery. It’s ideal for laboratories needing to carry out on-line or canister analysis of humid air streams while avoiding the loss of polar species, oxygenates and monoterpenes that can occur with other approaches to water management.
