Is the gas phase analysis data inaccurate? Eguis Flow Path Components: Building a Reliable Line of Defense for Results with Accuracy!
Date: 2025-12-04Read: 1
In gas chromatography analysis, the accuracy of results has never been a mystery - the sealing, reliability, and stability of each flow path component are the key determining factors for the final accuracy of detection data.
When you are still worried about the high price and long delivery time of imported valve groups, and struggling to match suitable valve groups for various applications, Egis has already delved into gas-phase core components, using "quality comparable to imports+localized high cost-effectiveness" to build a "stable foundation" for precision analysis in thousands of laboratories!
Full scenario product matrix, precisely adapted to each requirement
Whether it is routine analysis or extreme working conditions, Egis can provide customized flow path solutions.
1. Injection/switching valve (two position valve)
·Maximum number of channels: 14 channels, with a maximum aperture of 0.75mm
·Standard product withstand pressure of 100psi gas (maximum optional withstand pressure of 400psi gas)
·Temperature resistance of 200 ℃, suitable for the majority of conventional injection and flow path switching requirements

2. Standard flow path selector valve (multi position valve)
·Maximum number of digits: 16, with a maximum aperture of 1.0mm
·Standard product withstand pressure of 100psi gas (maximum optional withstand pressure of 400psi gas)
·Temperature resistance of 200 ℃, suitable for various gas injection analysis conditions

3. Selection valve with public discharge outlet
On the basis of the standard flow path selection valve, a "common discharge port" is added. In this way, the selected "sample inlet/outlet" is connected to the "common port", and the samples in the unselected "sample inlet/outlet" will not be blocked and will be discharged together from the "common discharge port". In this way, samples in unselected flow paths can also be updated in real-time, and there will be no "expired samples".

4. HavingIndependent discharge outletThe selection valve
Due to the fact that the design flow rate of the 'public discharge outlet' is less than the sum of the flow rates of the unselected ports, it will cause an increase in system pressure. If the sample will coking or produce other reactions due to the increase in pressure, then the 'independent discharge outlet' will be a better choice.
In this flow path, the selected "sample inlet/outlet" is connected to the "common port", and the samples in the unselected "sample inlet/outlet" will be discharged from their respective "independent discharge ports". This design can also effectively prevent mutual reactions among the samples.

All of the above products can choose additional features and performance standards
1. External blowing and sweeping
Inert gas protection to isolate bidirectional pollution between the experimental system and the environment
Compared to conventional gas chromatography valves, this product features a unique purge chamber design that surrounds the valve body with a purge chamber. When in use, by blowing the two ports of the cavity and continuously introducing low-pressure inert gas into the cavity, it can effectively isolate the interference of ambient air on the samples in the flow path. Similarly, it can also prevent toxic, harmful, odorous, flammable and explosive substances in the flow path from diffusing into the ambient air, effectively ensuring experimental accuracy and laboratory environmental safety.
Suitable for ultra (high) purity gas related applications, trace gas analysis, toxic and harmful substance detection, etc.
2. Low leakage version
Why choose Aegis? The preferred reason for import substitution!
Quality comparable to imports: stricter than industry quality control standards, each product undergoes multiple rounds of pressure resistance, temperature resistance, leakage rate testing, as well as long-term stable and reliable operation testing
High cost-effectiveness advantage: localized research and development production, with prices only one-third to one-half of imported products, significantly reducing procurement costs
Full scene coverage: from conventional to extreme working conditions, from standard configuration to customized requirements, one-stop solution for flow path problems
Quick response service: short delivery time, support for customization, timely resolution of after-sales issues
Egis not only provides products, but is also committed to providing "solid guarantees" for every precision analysis. Breaking the dependence on imports, making laboratory analysis more efficient, worry free, and reliable - Egis, trustworthy.
