CALIDUS 201

fast measurements
resistively heated columns
independent temperature on columns

A fast Gas Chromatograph (GC) - two columns for greater separation up to C44.

Calidus 201 drawing

Model 201 is comprised of 4 modules: a sample processing unit; 2 column modules (choice of columns available); and detector (either flame ionisation (FID), flame photometrics (FPD) or thermal conductivity (TCD). It can be used for virtually any gas and hydrocarbons up to C44.

There are two main benefits of having two columns: virtually doubling the column length gives greater separation; increased selectivity on stationary phases.

The Calidus 201 can be used:

in the laboratory
at line
as a transportable system or
on-line

A Calidus™ GC is capable of rapid measurements, has a footprint less than half of a research grade GC, and the capacity to do the work of 4 to 5 research grade GCs, making it the leading choice for gas analysis equipment and a cost effective measurement method.

The modular design lowers maintenance costs and increases flexibility to run different fluid mixtures.

The Calidus series of superior performance GCs uses ground breaking technology in the form of resistively heated columns. Using the stainless tube as the heater means that the traditional ovens for columns can be removed and the size of the system can be dramatically reduced.

The ethos of the Calidus series from day one was that a GC used in the lab should be the same GC when used as an on-line system for process control. This way the performance, methods and procedures developed for highly repeatable measurements can be directly applied to on-line systems.

Hydrogen Generator

These modular, stackable generators allow a safe hydrogen supply for carrier gas and FID operation without the requirement for storing high pressure hydrogen cylinders. These generators complete the portability of the Calidus GC and provide high purity hydrogen by electrolysis of water. The only utilities required are power and demineralised water to produce an uninterrupted supply of hydrogen gas.
