This molecular sieve S-trap is suitable for traping water vapour and also increases column and oxygen trap lifetime.

• Activated and ready to use
• Reduces water to less than 1 ppm
• Maximum flow: 1 l/min
• Reduces baseline noise from sensitive detectors such as ECDs and mass spectrometers

This trap can be regenerated by heating to 300 °C for three hours using a 50 to 70 ml flow of dry nitrogen.
