AU72507: Determination of Perchlorate in Environmental Waters using a Compact Ion Chromatography System Coupled with a Single Quadrupole Mass Spectrometer

Instrument Type: ICMS

This Application Update revises AN151 using a Thermo Scientific™ Dionex™ IonPac™ AS20 column set, on a Thermo Scientific™ Dionex™ Integrion™ HPIC™ system, coupled with a recently introduced Thermo Scientific™ ISQ™ EC single-quadrupole mass spectrometer. This study developed a method to accurately determine trace concentrations of perchlorate in environmental waters and provide a reference method for perchlorate analysts using IC-MS. The HESI-II electrospray improves ionization efficiency, eliminating the need to add organic solvents to enhance ionization.

AB72405: Fast Determination of Inorganic Cations and Low Mass Amines in Freshly Prepared and Moldy Green Tea Samples using IC-MS: Fresh Green Tea

Instrument Type: ICMS

Reliable analytical methods for food and beverage samples are required in order to report ingredients for food labeling requirements, and to ensure the absence of food contamination. In this application brief, separations of four inorganic cations, and three amines in a spoiled grape juice sample were achieved within six minutes. The analytes were detected serially, by suppressed conductivity and single quadrupole mass spectrometry in full scan (FS) and SIM (select ion monitoring) modes. This application updates AN269.

AB72406: Fast Determination of Low Mass, Inorganic Cations in a Ground Water Sample using IC-MS

Instrument Type: ICMS

Reliable analytical methods for food and beverage samples are required in order to report ingredients for food labeling requirements, and to ensure the absence of food contamination. In this application brief, separations of five inorganic cations in a ground water sample were achieved within six minutes. The analytes were detected serially, by suppressed conductivity and single quadrupole mass spectrometry in full scan (FS) and SIM (select ion monitoring) modes. This application updates AN269.

AB72404: Fast Determination of Inorganic Cations and Low Mass Amines in a Spoiled Cranberry Juice Sample using IC-MS

Instrument Type: ICMS

Reliable analytical methods for food and beverage samples are required in order to report ingredients for food labeling requirements, to maintain product quality, and to ensure the absence of food contamination and spoilage. In this application brief, separations of four inorganic cations and diethylamine in a spoiled cranberry juice sample were achieved within six minutes. The analytes were detected serially, by suppressed conductivity and mass spectrometry in full scan (FS) and SIM (select ion monitoring) modes. This application brief updates AN269.
