Solution Base Turn-key Analyzers
One of Gas Chromatograph applications is solution base turn-key analyzers. These analyzers include both standard analyzers such as NGA, LPGA, RGA, GGA, SimDis and non-standardized analyzers such as ones monitoring chemical process or environmental. The success of designing, assembling and testing analyzers greatly lies in provider’s comprehensive knowledges of the test standard and deeply understanding customer’s analysis requirements. The providers should also have in-depth experiences of the columns that perform required separations for long times to produce reliable and reproducible measurement results, practical working knowledges of instrument and instrumentations to minimize problems occurring during use, customer sample variations, and as simple as possible sample introduction. Keys of a reliable and accurate analyzers are to select right columns based on the sample and sample variations and to design the robust method with simplified instrument configurations for smooth analysis for a long time. Successes of the analyzes also greatly relies on good collaborations with end users including coach/training, update and customized modifications of standards or requirements, tech supports and follow-up.
With its strengths in column technologies, sample preparations and introductions, separations, instrumentations and data analysis, GS-Tek is proudly offering many solution base turn-key analyzers of both standard and customized ones. We make GS-Tek’s analyzer a difference. For examples, GS-Tek develops extended Natural gas analyzer (NGA) up to C16 for less than 40minutes, low level (ppm) moisture in chemical analyzer that gives our accurate and repeatable results, the analyzer used to monitor in-process acrylate reactions and alkaline oxides, low level formaldehyde or oxides in ambient air, and CO2 conversion developments.
GS-Tek offers the following analyzers by following the corresponding standard test requirements.
In addition to our broad standard analyzer offers show below, we are seeking for collaboration opportunities with potential customers for challenging applications. We strongly believe sample matter. GS-Tek has developed novel technique to partition gas-liquid mixture samples under extreme conditions such as high temperatures and pressures so to simplify chromatograph analysis, this technique will yield reliable and accurate measurements for chemical process samples. GS-Tek has come up with a simple measurement approach for measuring impurities in highly pure gases that are widely used in new energy research, semi-conductor industry, and environmental monitoring for much less cost than standard analyzer. Examples are H2S, CO/CO2, ASH3, PH3, Cl2, HF, Ethylene oxide, noble gases and so on. Please let us know your interests and needs by emailing to info@gs-tek.com.
GS-Tek is happy to provide its 2nd opinion for interesting party who works on solution base analyzer, as we feel that our column expertise be a practical help. GS-Tek is equally happy to assist needy customers to do trouble shooting, repair, calibrate, or update its existing analyzers. In bottom line, GS-Tek wants solution base analyzer work!

Nitrogen Evaporator:
Nitrogen Evaporator is to use nitrogen gas purging along with heating to evaporate excessive solvent in a liquid sample. The concentrations of interesting components in the sample are increased by a few folds, easy to use for analysis or further sample process.
Nitrogen evaporators are widely used in environmental and biological areas.
Total Solution of Hot Stream Sample Analysis:
Rear time monitoring changes of a hot stream composition in a chemical reaction process is very critical for both reaction process control and safety of the reaction device. An example is acrylic acid reaction. The oxygen level is used to detect completion of the reaction. Excessive high aldehyde level may cause exposition of this reaction device.
The major components of a hot stream are air, moisture and raw reactant materials such as butenes, methanol. The content levels of oxygen from air and reactant material are changed over reaction time from high level (percentage) to ppm level (completion of reaction). A hot stream temperature is usually above 100 Degree C, the pressure of the hot stream is slightly above ambient pressure. The reactant(s) are very viscous and prone to polymerization or dimerization when a locally concentrating occurs from changes of stream temperature, flow area, or pressure. When a hot stream sample is taken from process, both the temperature change from handling and duration of the sample transportation to analysis may not able to produce correct real time data. All the level change, physio-chem property, and reactivity cause challenges for in-line monitoring and analysis.
GS-Tek develops a total solution for analyzing hot stream samples to give a real time result. The key technology of this total solution is an in-line sampling device. This sampling device is to isolate gaseous phases from liquid phases (moisture, raw material, reactant products, and final product) with a measureable sample mass and volume of the gaseous phase. Both gaseous sample and liquid sample will be analyzed on an off-line gas chromatograph analyzer to produce a complete result of gases and liquid components. This sampling device is easy to operate in-line, both gaseous phase and liquid phases sample can be easily and safely transported to lab for analysis.
This total solution of hot stream sampling, isolation and gas chromatography base analyzer has been successfully used in a few chemical processes of methyl acrylic acid and acrylic acid for over years. This total solution can be extended with minor customizations to other chemical reaction processes, and researches in environmental, combustion, coal chemical process, new catalyst development.
