氢化物发生原子吸收光谱仪

Hydride Generation AAS

氢化物发生原子吸收光谱仪

Hydride Generation AAS — Atomic Absorption Spectrometers

Arsenic, selenium, antimony and similar elements form volatile hydrides, and separating them from the matrix gives far lower detection limits than conventional flame work. We offer continuous-flow, flow-injection and batch hydride generators, systems with an integrated cold vapour mercury module, multi-element versions and fully automated units with autosamplers. Choose by sample throughput, reagent consumption and which elements you report.

Applicable standards

Ph. Eur. 2.2.22 Atomic absorption spectrometry USP <852> Atomic Absorption Spectroscopy ISO 11969 Water quality — Determination of arsenic by AAS US EPA Method 7062 Arsenic by hydride generation US EPA Method 7473 Mercury in solids and solutions IEC 61010-1

How to specify

  1. Flow-injection designs use less reagent per sample than continuous-flow systems.
  2. Add the cold vapour module if mercury is on your reporting list.
  3. State whether pre-reduction steps are needed for your arsenic or antimony species.
