ABB Totalflow NGC8206 Startup Manual page 6

Precautions:
•
DO NOT use any type of plastic, Teflon or Teflon-lined
braided steel tubing. Use only good quality, clean stainless
steel chromatographic grade transport tubing for carrier,
calibration gas and sample lines. Use of poor quality stainless
steel tubing will generate unsatisfactory results.
•
Use only high purity 99.995% grade helium or better for carrier.
•
Sample Transport Tubing Lengths: When sample conditioning
modules are used, the sample transport tubing run can be up to
50 feet. Lengths longer than 50 feet must adhere to the rules of
calculated lag time per the Calculating Lag Time section in the
System Description chapter of the NGC8206 User's Manual.
If a sample conditioning module is not being used, the sample
transport tubing should be 1/16-inch tubing and no longer than
ten feet.
•
Purge all lines prior to connecting to the NGC.
