MAK Gas Chromatograph

Image module

2191 is next version of ‘MAK GC 911M’. The MAK ANALYTICA 2191 is designed out of our varied experience in the field of analytical instrumentation and Gas Chromatography in specific. Our team comprises of specialists from engineering, electronics, application and other related disciplines, who constantly strive to improve the performance of our instruments.
The MAK ANALYTICA 2191 is suitable for Quality control. R & D, routine analytical requirements, & most of the applications. The modular concept for additional accessories, facilities, detectors and serviceability.

Temperature Control

The oven, Injector Detector and auxillary channel temperatures are controlled precisely by user friendly
Microcontroller with 4 line alphanumeric display has facility of 9 step temperature profile for oven heating and over 60 methods storage capacity with alphanumeric naming.
All the parameters, (set and actual), are displayed. The higher temperature cut off (adjustable) are provided for all the channels. Flame Ionisation Detector is designed to give high sensitivity, while Thermal Conductivity Detector is with minimum cell volume to get maximum sensitivity.

Modular construction makes the instrument versatile to upgrade with add-on modules as and when
required. This also makes it convenient from service point of view so as to keep the down time to the
minimum.
The Machine is tested to ruggedness and robustness. % RSD is found to be less than 2% under test
conditions.
With our prompt after-sales service and application support, we have wide customer base in all kinds of
industries.
