Speciated Arsenic Analysis in Wine Using HPLC-ICP-QQQ Validation of an Extended FDA Elemental Analysis Manual Method

Speciated Arsenic Analysis in Wine Using HPLC-ICP-QQQ: Validation of an Extended FDA Elemental Analysis Manual Method

The FDA Elemental Analysis Method (EAM) §4.10 describes arsenic (As) speciation in fruit juice by HPLC-ICP-MS. Validation data supporting extension of the EAM method to include wine is presented.

 
Quantitation of PAHs in Used Engine Oil Using GCxGC and Time-of-Flight Mass Spectrometry

Quantitation of PAHs in Used Engine Oil Using GCxGC and Time-of-Flight Mass Spectrometry

This application note describes how using a combination of GCxGC and TOFMS PAHs are separated from matrix interferences using both orthogonal column phase selectivity and additional extracted ion mass precision.

 
Determination of Lead in Powdered Milk using AAS

Determination of Lead in Powdered Milk using AAS

This application note demonstrates a simple method for the analysis of lead in powdered milk without the need for sample digestion using AAS.

 
Simultaneous Total and Speciation Analysis of Volatile Arsenic Compounds in Gas and Liquefied Gas Samples using GC-ICP-MS

Simultaneous Total and Speciation Analysis of Volatile Arsenic Compounds in Gas and Liquefied Gas Samples using GC-ICP-MS

This application note describes a novel gas sampling system that enables simultaneous GC-ICP-MS analysis of total and speciated volatile arsenic compounds such as arsine in gas and liquefied gas samples.

 
Determination of Diclofenac and Its Related Compounds using RP-HPLC-ICP-QQQ

Determination of Diclofenac and Its Related Compounds using RP-HPLC-ICP-QQQ

Chlorine-based drugs, metabolites and related compounds were separated using reversed phase (RP) HPLC. Quantification was by compound-independent calibration, based on measuring the chlorine (Cl) heteroatom using triple quadrupole ICP-MS (ICP-QQQ).
