the XRF analyzer was selected by HUD for lead based paint testing primarily because -
correct answer-it may be the most cost effective technique

paint samples that test "inconclusive" by XRF should have confirmatory samples redone by -
correct answer-atomic absorption analysis

submissions of small amounts of substrate materials with paint samples for laboratory
analysis will - correct answer-over and underestimate the lead concentration if results are in
percent by weight

to collect water samples for laboratory analysis for lead - correct answer-allow the water to
stand in the pipes for at least 6-12 hours before collecting the sample

, dust vacuum sampling might be used for - correct answer-rough concrete and carpets
