Unboxing 4 Unboxing Each BRECHTEL STAP is inspected and tested in-house at BRECHTEL to ensure out of the box operation upon delivery. Prior to opening, inspect the packaging container and ShockWatch impact indicators. Carefully open the package and inspect the instrument and any accessories for broken parts, scratches, dents or other signs of damage incurred during shipping.

Page 10: Stap Overview
The STAP has a single sample ﬁlter and a single reference ﬁlter through which the sam- ple ﬂow passes downstream of the sample ﬁlter. For applications requiring multiple sample channels, Brechtel offers the Model 2901 TAP with 8 sample ﬁlter spots and 2 reference ﬁlter spots.

This analysis is not unique to the PSAP. Unfortunately, this assumption does not take into account the ﬁlter material or the prop- erties of the bulk developed in depositing the particles both on and in the ﬁlter, but we 83-00036-01A STAP 9406 Page 10 of 46...
