HAM7 chamber FTIR samples taken for contamination mapping and Hexane test wipes taken to determine contamination

Document #:

LIGO-E2100134-v4

Document type:

E - Engineering documents

Abstract:

Following the initial FTIR results taken in HAM7 E2100122, 10x Hexane FTIR samples, (Labelled S1, S2...., S10), were taken in various grid locations. 2 of these samples were taken after attempting to clean with 2-propyl and DI water....

One of the attached documents lists the 10 areas we swabbed. eg Swab area 1 = vial labelled S1, and so on

4 additional Hexane test samples (using FTIR sample swabs). (Labelled T1, T2, T3, T4), were taken to use to attempt to determine the source of the contamination.

1 control was kept with each kit

The vials were shipped out in the same "kits" that they arrived (eg the vials that arrived in kit #1 and that we used were shipped out in kit #1 and so on).
