Static diluterBy precisely controlling the volume ratio of diluent to sample, sample dilution can be achieved. Its working principle is based on the "proportional method", which obtains solutions of different concentrations by changing the dilution liquid volume. In gas dilution, equipment usually uses absolute pressure sensors to measure pressure changes, or uses high-precision mass flow controllers (MFCs) to control gas flow and achieve precise dilution. Liquid dilution may be automatically completed through components such as electronic scales, volumetric flasks, and dispensers.

　　Static diluterIntroduction to Technical Features:

high precision

Using high-precision pressure sensors or mass flow controllers to ensure the accuracy of dilution ratios. For example, the mass flow controller of some devices can achieve an accuracy of ± 1% F.S, with a repeatability accuracy better than ± 0.2% F.S.

The dilution ratio range is wide, with a primary dilution of 100-200 times and a secondary dilution of over 10000 times, meeting the analysis needs of trace samples.

Multi channel design:

Equipped with multiple channels (such as 6 channels, 7 channels), it can simultaneously process multiple samples or standard gases, reducing workload and saving standard gases.

Independent control between channels to avoid cross contamination.

Inert flow path:

All pipelines are treated with inertization (such as siliconized stainless steel, PEEK material) to avoid reaction between the sample and the pipeline, ensuring the reliability of the analysis results.

The flow path volume is small (such as less than 200 μ L), easy to clean, and reduces residue.

Intelligent operation:

Adopting PLC control system or touch screen interface to achieve operation without computer and simplify the process.

Support method editing, storage, and dilution process traceability for easy experimental recording and data analysis.

Some devices support WIFI communication and can be remotely controlled through a tablet computer.

Safety and Environmental Protection:

The static configuration method avoids the emission of standard gases into the environment and meets environmental protection requirements.

Equipped with automatic leak detection function to prevent dilution failure or waste of standard gas caused by gas leakage.
