General Chapter/Section(s) Expert Committee(s): No. of Commenters: <852> Atomic Absorption Spectroscopy General Chapters—Chemical analysis 3 Qualification of Atomic Absorption Spectrophotometers Comment Summary #1: Under Precision, the commenter indicates that replicates of the 0.10-µg/mL Zn ...
UV–vis spectrophotometers using matched quartz cuvettes, but this is currently not suitable for HPLC detectors. Holographic gratings are typically used within HPLC detectors because of their greater resolving power. This means that it is extremely unlikely the detector would fail at 200 nm if other...
The changes introduced in this general chapter are discussed in the first White Paper of this series: What has Changed with the New Version of USP <1058>?1. In this White Paper, we will look at the impact of these changes on a regulated laboratory, as we discuss some of the practical ...
注意,探测器2可安装在可移动臂上。 Turbidity also can be measured with a standard photoelectric filter photometer or spectrophotometer, preferably with illumination in the blue portion of the spectrum. Nephelometric measurements require an instrument with a photocell placed so as to receive scattered, r...
