Abstract |
This report provides results for the verification testing of LeadPaintCheck test kit for lead-based paint by Industrial Test Systems, Inc. The following is a description of the LeadPaintCheck test kit, based on information provided by the vendor. The information provided below was not verified in this test. LeadPaintCheck is a semi-quantitative test kit that can detect the presence or absence of lead in paint. To evaluate a sample, a half-inch circle paint sample is collected, the paint sample is cut up in smaller pieces, and then it is homogenized in the ACID-1 acid solution. Lead in the Homogenized Paint (HP) sample is solubilized as Pb+2 by the acid. The HP sample is then diluted 1/500 (100 microliters (Yl) per 50 milliliters (mL) of water). The procedure for measurement of lead in the diluted sample uses 4 mL of the HP extract, which are added to the built-in photocell of the eXactR LEADQuick. Photometer. The sample is zeroed, two drops of Pb-2 Buffer are added to make the solution mildly alkali (pH 9-10), and an eXactR Strip Pb-3 is then dipped in the sample for 20 seconds with gentle motion. The PB-3 strip simultaneously adds a porphyrin colorimetric indicator and mixes the solution. After one minute, in which time the porphyrin and Pb+2 forms a colorimetric complex, the eXactR LEADQuick. Photometer measures the optical density (color) as an absorbance number (abs). The 'SCabs' O value will be dependent on the amount of lead that is present: the higher the abs value, the higher the lead concentration in the sample. |
