New Products SRM SRM 955, Lead in Blood, is intended for use in evaluating the accuracy of lead determinations in blood and in calibrat ing instrumentation for these determina tions. Four individual concentrations of lead in porcine blood are provided in polyethylene bottles. Nominal certified concentrations, in jtg/dL and /tmol/L, are 5.7, 0.27; 30.5, 1.47; 49.4, 2.38; and 73.2, 3.53. NBS 419 Solution standards Spectrochemical solution standards are designed to optimize the performance of AA, AFS, DCP, ICP, and XRF instru mentation. Certificates specifying ana lyzed data for more than 70 elements accompany each solution. Typical error of added elements is 0.2-0.4%. Sherba Analytical Lab Products 420 Hydrophilic gel FMP-activated hydrophilic gel, designed for use in affinity chromatography and as a carrier for immobilization of en zymes, can couple with amino or thiol groups of ligands. Stable, leak-resistant secondary amine or thioether bonds are
formed between the matrix and ligand. BioProbe International, Inc. 421
