A.1 Introduction
Appendix B consists of the following sections:
• B.2 Filter Compatibility
• B.3 Physical Dimensions
• B.4 Nominal Transport Times
A.2 Filter Compatibility
The following table shows sample filter requirements.
If you are monitoring non-corrosive target gases,
use filter type A, (P/N 780248), a sample line dust/
particulate filter.
For monitoring corrosive gases, such as chlorine
(Cl ), hydrogen fluoride (HF), hydrogen chloride (HCl),
2
and hydrogen bromide (HBr), sample lines in a dusty
environment or for outdoors, use filter type B, (P/N
1830-0055), or type C, (P/N 1991-0147) filter assembly
for corrosive gases. The Teflon membrane particulate
filter is designed to prevent dust and dirt greater than
one micron from entering the sample line. Unlike
standard particulate filters, it does not exhibit sample
loss with corrosive monitoring.
The one micron Teflon membrane contained in the
filter housing (P/N 0235-1072, 100 per pack) should
be replaced every 30 days.
Filters have an arrow on the side of the filter pointing
in the direction of airflow toward the Vertex M system.
Replacement of filters is site dependent.
Filter A - P/N 780248
Filter B - P/N 1830-0055
Filter C - P/N 1991-0147
