Turn-Key Applications

CONSCI's turn-key applications are custom built instrumentation and after-market customization of gas chromatographs and GC/MSs including detector and valve additions. The two most versatile systems are the CALX2 Gas Chromatograph and the Gas Dragon FTIR. The CALX GC is highly flexible with options available for many applications. In addition, CONSCI will wrap their engineering might around your specific project to find the best solution to your needs.

CALX2 Gas Chromatograph

PDF Info Sheet

An economical, compact, and simple-to-use instrument designed as a cross-over platform between a laboratory and fully unattended process control environment.

The CALX2 Gas Chromatograph is designed to be an economical, compact and simple to use instrument suitable for the laboratory or as a crossover platform between the lab and a fully unattended process control environment. To fill those needs a modular component based, rack-mount design was chosen, keeping the applicated cost below both laboratory style instruments as well as classified process instruments. In addition to saving money and space, it maintains the esthetics of the manufacturing environment.

Part of the design criteria was to build the instrument with inexpensive, replaceable sub-assemblies. The Calx2 is designed such that up to five valves, two detectors, and four heated column zones are possible. Detectors available are TCD, PDID, and FID.

The typical configuration uses a PDID for part-per-billion level measurement of atmospheric contaminants in both bulk gases like hydrogen, nitrogen, oxygen, argon as well as aggressive/reactive electronic gases like arsine or hydrogen chloride. Many custom flow-paths are available with block and bleed valving, backflushing, heart-cutting, and ’smart‘ cutting.

System Specifics

Carrier Gas: Helium
Pneumatics: 80 psig clean dry air or inert gas
Electrical: 20 amp circuit

The greatest strength in our turn-key instrumentation lies in simplicity and ease of use. We take the time before building to properly design each system, and because we take this approach, each application is highly unique. This uniqueness does not incur greater expense, but it does mean each application should be explored with an engineer.

CALX Gas Chromatograph

PDF Info Sheet

An economical, compact, and simple-to-use instrument designed as a cross-over platform between a laboratory and fully unattended process control environment.

The CALX Gas Chromatograph is designed to be an economical, compact and simple to use instrument for customers in need of a crossover platform between a laboratory and fully unattended process control environment. To fill that need a modular component based, rack-mount design was chosen, keeping the applicated cost below that of a laboratory style instrument as well as below a classified process instrument. In addition to saving money and space, it maintains the aesthetics of the manufacturing environment.

Part of the design criteria was to build the instrument with inexpensive, replaceable, generic, non-proprietary subassemblies. The CALX was designed to use up to three valves, two separately controlled oven zones, and either a PDID or TCD detector. It can also be used as an inlet system for a mass spectrometer or atomic emission detector.

The typical configuration uses a pulsed discharge detector for the trace analysis of atmospheric contaminants including hydrogen, nitrogen, oxygen, argon, carbon monoxide, methane, and carbon dioxide in aggressive/reactive electronic gases. Custom models have been configured to measure over eleven impurities in nitrogen trifluoride. In addition to the analytical flow-path, by-pass and block-and-bleed provisions for both standard and sample can be provided.

System Specifics

Carrier Gas: Helium for PDID; Hydrogen, nitrogen, argon, or helium for TCD
Pneumatics: 80 psig clean dry air or inert gas
Electrical: 20 amp circuit

GasDragon FTIR

PDF Info Sheet

The GasDragon FTIR spectrometer is a fully integrated gas analysis system designed for a wide range of applications. It can quickly and easily alternate between product component analysis at percent levels and trace analysis of impurities at sub-part-per-million levels.

FTIR spectroscopy is an extremely stable technique for gas analysis. Once the instrument is characterized, only performance checks are needed to validate quantitation. The Gas Dragon FTIR spectrometer includes customized calibration recipes for each customer's specialized needs.

The optical bench is the robust and reliable Thermo Nicolet iS5, and the instrument panel is designed to safely handle reactive, corrosive, and other analytically challenging gases with as little risk to the operator as possible. Precision is less than 0.05%. Typical detection limits for various matrix gases are listed in the info sheet above.

Custom Instrument Development

Custom configurations can be made for specialized applications such as determination of trace impurities in electronic gases or automated sequencing of standard and calibration gases.

FTIR Calibration Spectra

We offer FTIR calibrations in SPC file format for a variety of gases using 1 cm-1 and 0.5 cm-1 resolution at 50°C. Other resolutions and temperatures are available upon request, and the file format can be translated into a variety of software formats.

Typical calibrations include a five data point curve, and in addition to calibrations for trace analysis, we can also provide pure matrix gas spectral files that can be used for abstractive analysis.

Example FTIR calibration spectra of nitric oxide (NO) at 0.5 cm-1 resolution.
