Dilute the standard series, the blanks and sample digests 1 + 9 (v/v) with lanthanum - solution (6.3A) or with cesium - lanthanum solution (6.3B) (see remark 3) and mix. Measure in the diluted standard series, the diluted blanks arxJ the diluted sample digests the Ca concentration with flame AES at a wavelength of 622.0 nm, using an air-acetylene flame. [Pg.49]

Measurement - Measure in the standard series, the blanks and sample digests the Ca concentration with the ICP-OES at a wavelength of 317.933 nm. At this wavelength a (fitted) background correction is used. [Pg.54]

A 0.2-g sample of amylopectin was analyzed to determine the fraction of the total glucose residues that are branch points in the structure. The sample was exhaustively methylated and then digested, yielding 50 /tmol of 2,3-dimethylglucose and 0.4 /tmol of 1, 2, 3, 6-tetramethylglucose. [Pg.236]

In order to derive a quantitative relation between emission Intensity as measured by EMI and actual metal content, cell samples were subjected to graphite furnace atomic absorption (GFAA) analysis (14). Atomic absorption experiments were performed both on cells which had been stained with a fluorescent reagent and on cells not exposed to a lumlnophore. After EMI analysis, 50 fiL of cell suspension were withdrawn from the 0.30 mL of sample used for EMI and were digested In 150 iiL of concentrated HNO3 for 90 minutes at 85° . These solutions were then diluted to 1/10 of their concentration with deionized water, and the 150 liL of these diluted... [Pg.87]

Pd removal was determined as follows. An aliquot of a representative liquid or solid sample was accurately weighed and subsequently digested by refluxing in nitric and/or hydrochloric acid using a closed vessel microwave procedure (CEM MARS5 Xpress or Milestone Ethos EZ). Cooled, digested samples were diluted, matrix matched to standards, and referenced to a linear calibration curve for quantitation an internal standard was employed to improve quantitation. All samples were analyzed by an Inductively Coupled Plasma Mass Spectrometer or ICP/MS (Perkin Elmer SCIEX Elan DRCII) operated in the standard mode. [Pg.54]

Nagoumey and Madan [20] have considered both AAS and ICP-AES as reliable measurement techniques for the determination of metal components in mixed-metal/phosphite stabiliser systems in PVC. For reasons given elsewhere (Section 8.3.2.4), in this case ICP-AES was considered the technique of choice for most metal stabiliser determinations, while AAS remains a useful method to corroborate the ICP-AES results. For the determination of tin in rigid PVC by means of HG-AAS, the main effort has been to develop a sample digestion procedure [118]. Tin and Ti from a PVC potable... [Pg.611]
