Apparatus for measuring surface particulate contamination

An apparatus for measuring surface particulate contamination comprising:

• a tool having:
• a body portion having a large diameter section defining a surface and a small diameter section extending from said large diameter section;
• a particulate collector removably mounted on said surface of said large diameter section;
• a spindle extending from said small diameter section, said spindle having an indicator formed thereon;
• a spool slidingly mounted on said spindle;
• and
• a spring disposed between said small diameter section and said spool for biasing said spool away from said small diameter section, wherein said indicator is covered by said spool when said spring is in an uncompressed state and said indicator is not covered by said spool when said spring is in compressed by said spool;
• a mask having an opening of known area formed therein;
• and
• a flexible connector connecting said tool to said mask.

A tool for collecting a contamination sample from a target surface, said tool comprising:

• a body portion having a large diameter section defining a surface and a small diameter section extending from said large diameter section;
• a particulate collector removably mounted on said surface of said large diameter section;
• a spindle extending from said small diameter section, said spindle having an indicator formed thereon;
• a spool slidingly mounted on said spindle;
• and
• a spring disposed between said small diameter section and said spool for biasing said spool away from said small diameter section, wherein said indicator is covered by said spool when said spring is in an uncompressed state and said indicator is not covered by said spool when said spring is in compressed by said spool.
