Determination of total and leachable arsenic and selenium in soils by continuous hydride generation inductively coupled plasma mass spectrometry

A hydride generation flow system for determination of arsenic and selenium by total reflection X-ray fluorescence spectrometry

“…The system of hydride generation was built with an MP-8 peristaltic pump (Ismatec, Zurich, Switzerland), 0.8-mminternal-diameter polyethylene tubing, Tygon tubing (Ismatec) and a liquid -gas phase separator made from a 5-ml plastic syringe, similar to that described elsewhere [8].…”

Determination of selenium in nickel-based alloys by flow injection hydride generation reaction cell inductively coupled plasma mass spectrometry

“…Several reports show that the sensitivity and detection limits of hydride-forming elements were greatly improved when they were introduced into the plasma as hydrides. [22][23][24][25] Selenium hydride sample introduction techniques have been applied in several previous publications. [26][27][28][29] In the present investigation, a simple, laboratory-built hydride generation system was used as the sample introduction device for FI-ICP-DRC-MS.…”

Determination of different oxidation states of arsenic and selenium by inductively coupled plasma-atomic emission spectrometry with ion chromatography

“…Therefore, the determination of the chemical form is important [2,3]; but at present a speciation analysis is not required from a legal point of view. HG has been used in combination with AAS, ICP-AES, and ICP-MS to increase the sensitivity for these elements [4][5][6][7][8]. When HG is used, As(V) and Se(VI) are reduced to As(III) and Se(IV), respectively, by the reducing reagents for the generation of hydrides.…”
