AbstractThe humidity of 4.9 x 10[-6]m[3] samples of air was measured by GLC. They were captured in a Teflon-lined syringe that is heated to 33 degrees C. The standrd deviation of sets of results at -15 degrees C and 20 degrees C dewpoint were 0.8 degrees C and 0.15 degrees C respectively. Samples stored for up to 7200 s tested within 6% of the correct humidity ratio. Correct technique was found to be important.
