Martine Lado, an agent in the Irvine, Calif., office, said she coached brokers to leave parts of applications blank to avoid prompting verification if the borrower's job or income was sketchy.
Instrument response was evaluated initially, after every 10 samples, and at the end of each analytical run using a calibration verification standard and blank.
Quality control measures included analysis of initial and continuous calibration verification standards, procedural blanks, duplicate samples, and spiked samples.
Quality control measures included initial and continuous calibration verification standards, procedural blanks, duplicate samples, spiked samples, and the National Institute of Standards and Technology Standard Reference Material for trace elements in water (NIST SRM 1643d).
Experimental verification of the optimized blank is done by circular grid analysis technique.
Included in the ICPMS analytical runs were the following quality control samples: calibration verification (every 10 samples), reagent blanks (every 10 samples), method blanks (one per batch), matrix spikes (10% of samples), sample duplicates (10% of samples), and NIST SRM 2709 (one per batch).
Quality control measures included: analysis of initial calibration verification standard, continuous calibration standard, procedural blanks, and duplicate samples.
For the ICP-MS measurements, a laboratory quality control regiment is described that included use of internal standards, interspersed analysis blanks, intra and inter-run precision through dilution verification and duplicate preparation, and importantly inclusion of standard reference materials (SRMs).
Quality control measures included: analysis of initial calibration verification standard, continuous calibration standard, procedural blanks, duplicate samples, spiked samples, National Institute of Standard and Technology Standard Reference Material (NIST SRM) 1643e-trace elements in water and NIST SRM955b-lead in blood.
