Routine analysis of volatiles from fruit juices can be sampled and concentrated using a static headspace method and rapidly analyzed by high-speed GC.

The author configured a purge-and-trap GC-MS system that simultaneously improved chromatographic resolution and reduced analysis time.

The authors demonstrate a new detection method for various anions and cations separated by ion chromatography and point out the main advantages of this method.

Despite their different levels of technological maturity, CE and LC coupled with electrospray ionization MS techniques can be operated at the same level of automation. However, they differ in their configuration, selectivity, sensitivity, and method development.

The authors describe the results they've achieved by using water heated to 100–240 ºC as a liquid eluent for reversed-phase HPLC instead of an organic modifier. They point out that this alternative avoids many of the problems – toxicity, flammability, and cost – associated with organic modifiers.

The authors evaluate a new chiroptical detector's sensitivity for various chiral compounds, linear dynamic range, and relative response with different solvents.

The authors developed an ion chromatography method to separate 31 cations in a single chromatographic run using inductively coupled plasma–mass spectrometry, liquid scintillation counting, and gamma counting. The high-level radioactive waste samples contained trace radionuclides in concentrations of only a few hundred disintegrations-per-minute-per-milliliter.

With the goal of developing an analytical method for the fast analysis of vitamins in a complex matrix, the authors created a method that used in-line and complementary HPLC with photodiode-array and MS detection techniques.
