Restek 22015: Moisture Trap with Saturation Indicator, for Stable and Reliable GC Analyses
The Restek 22015 moisture trap with saturation indicator is an essential accessory for ensuring the purity of gases used in GC systems, particularly in medical, pharmaceutical or environmental contexts requiring rigorous control. This model, equipped with 1/4" connections, reduces residual moisture to below 10 ppb, protecting highly sensitive detectors from water-induced interference.
The highlight of the 22015 is its integrated visual indicator: the colour change from blue to pink immediately identifies saturation at 5% relative humidity. This simple but effective mechanism eliminates maintenance uncertainties and provides continuous monitoring without additional instrumentation.
This trap is pre-purged to ensure quick commissioning, limiting waiting times during installation. Its thick glass body plays a key role in preventing oxygen or water ingress, thus maintaining the integrity of the carrier gas used in the analyses. A 40 µm frit filter protects downstream components such as needle valves and flow regulators from fine particles, which is essential for maintaining measurement accuracy in medical chromatography systems.
The 22015 model supports a maximum pressure of 100 psig, making it ideal for helium or nitrogen lines frequently used in laboratories. Its compact size (33 x 5.1 cm) facilitates integration into existing environments without the need for additional modifications.
Using a high-performance moisture trap is essential for obtaining stable and reproducible results, especially when working with low-concentration analytes or complex matrices. The Restek 22015 is therefore a safe choice for enhancing the reliability and quality of GC analyses in medical, environmental, and regulatory fields.
