Ion Chromatography

Monoamine neurotransmitters (adrenaline, dopamine, noradrenaline, and acetylcholine) are released from the brain and peripheral nervous system in minute amounts.

Market Profile: Ion Chromatography

Ion chromatography (IC) is a similar technique to HPLC except that the detector of choice is usually a conductivity detector. IC is well suited for the analysis of a variety of inorganic and organic anions and cations.

The Column spoke to Dr Ailsa Benton - an "ice core" analytical scientist from the British Antarctic Survey (BAS) research team - about the role of chromatography in climate change.

Ion chromatography (IC) is an important analysis tool for chromatographers. Typically, emphasis is placed on the hardware components and chemistry to achieve the ideal level of separation. However, the flow path itself is often overlooked, and there are some relatively simple steps that can be taken to ensure that the system's flow path positively affects the overall chromatographic results achieved.

Computer-based methods can simulate separations for a wide variety of analytes, columns, and eluents.

A summary of the latest in new ion-exchange phases for ion chromatography, with a focus on general aspects of phase design and then a review of anion-exchange and cation-exchange columns introduced in the past few years

The authors present the most common and fundamental techniques that address common matrix issues and discuss the critical chemistry considerations.

The speed of IC has been limited by pressure and flow limits of the hardware. Recent advances are enabling faster IC separations.

From the invention of eluent suppression to today's "just add water" concept, pivotal developments over the last 40 years are chronologically highlighted from a chemical and instrumental viewpoint.

Positron emission tomography (PET) is one of the most powerful non-invasive diagnostic tools for tracing organ functioning. Quality control of the short-lived radiopharmaceuticals is challenging, not least because of the tough time limits, the radiation issue and the near nanomole radiotracer quantities.

Positron emission tomography (PET) is one of the most powerful noninvasive diagnostic tools for tracing organ functioning. Quality control of the short-lived radiopharmaceuticals is challenging, not at least because of the tough time limits, the radiation issue, and the near nanomole radiotracer quantities.

Risedronate, a pyridinyl bisphosphonate, is one of the most popular first-line drugs in the treatment of osteoporosis, Paget's disease, and other bone fragility conditions. In October 2010, the United States FDA approved a second-generation risedronate in a delayed-release formulation.

Metrohm Application Note

This article describes a 2D matrix elimination ion chromatography method to analyse samples containing high levels of matrix ions.

The presented ion chromatographic method is used for the simultaneous determination of HF, HNO3, H2SO4, short-chain organic acids and H2SiF6 in acidic texturing baths that are used in the wet chemical etching process of solar cell production.
