Preparing Biological Samples for Elemental Analysis by ICP-MS
Andrew Ryan, Analytik Jena GmbH
The transition from Atomic Absorption Spectroscopy (AAS) to Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) has been gradual for the clinical industry over the past two decades. Both flame AAS and graphite furnace AAS techniques have served the industry well in hospitals, clinical institu...

Direct Determination of Trace Elements in Body Fluids Using ICP-Mass Spectrometry
Dr. René Chemnitzer, Analytik Jena GmbH
The better understanding of the relevance of various elements in metabolic and other processes in organisms leads to increased interest in the analysis of biological samples like body fluids. Here, the focus is on supply of essential elements and detection of toxic elements. Fast and more sensiti...

Speciation of arsenic in apple juice by LC-ICP-MS
Andrew Ryan, Peio Riss, René Chemnitzer, Analytik Jena GmbH
The different physico-chemical forms of most elements vary in terms of mobility, toxicity and bioavailability. For example, arsenic species such as the inorganic trivalent arsenic (As III) and pentavalent arsenic (AsV) are highly toxic whereas the organic forms as monomethyl arsenic (MMA) and dim...

Background Correction In AAS - Can You Really Trust It As Much As You Do?
Oliver Büttel, Analytik Jena GmbH
Background Correction (BGC) is an essential part of any spectrometric analysis. Typically a non-specific signal, the spectral background, is superimposed on the analyte-specific signal and needs to be excluded to obtain the net analyte signal. Different techniques have been developed to distingui...

Fast and Reliable TOC/TNb Determination in Saline Water Using the multi N/C® Series
Bernd Bletzinger, Analytik Jena GmbH
In many areas of application - extending far beyond drinking and waste water analysis - a fast and reliable TOC/TNb determination is required. The catalytic high temperature combustion with subsequent selective and sensitive detection of the combustion products CO2 and NO is an established determ...
