John L Molloy (Fed)

John's main focus while at NIST has been the study of sample heterogeneity at small mass levels. He has pursued this topic in an effort to develop a method for NIST to certify SRMs at sample sizes within the low milligram and microgram mass regimes. Another program he is involved in concerns development of reference materials to help quantify Pb levels in paint in children's products. He has also developed software using Visual Basic to facilitate mixing of Fossil Fuel SRMs. John has used a wide variety of analysis techniques at NIST including µXRF, WDXRF, ICPOES, ICPMS, and INAA.
