Compact Gas Chromatograph - LDetek MultiDetek2 Description：

User's Manual Datasheet

Modular and Flexible Multi-Detector Configuration.

Features

Pre-configurable according to application requirements: ready-to-use device.

Stand-alone instrument for multiple trace impurity measurements.

Multiple detectors: PED, TCD and FID.

Wide measurement range covers sub-ppb to percent measurements.

PPB sensitivity with argon, helium or nitrogen carrier gas (PlasmaDetek)

Easy to use and maintain, with large touch screen interface, keyboard connection and easy access panel.

Ethernet connection allows remote operation.

Designed for both industrial and laboratory use, MultiDetek2 measures multiple trace impurities, with many configurations possible in the same instrument. Based on the new generation of LDetek’s Plasma Emission Detector, versions are also available featuring FID and TCD sensors to extend the measurement capabilities. MultiDetek2 uses argon, helium or nitrogen as carrier gases.

The wide operating range starts from sub-ppb up to % level measurements for maximum flexibility. The instrument is also designed for simple operation with a user-friendly 8.4” touch-screen interface and front opening door to allow easy access for maintenance.

The standard industrial compact GC model MultiDetek2 can also be integrated inside a stainless steel certified (ATEX-IECEx) purged enclosure to be used in Zone1 and Zone 2 hazardous areas.
