Technology
An analytical technique wherein gas chromatography is coupled to mass spectrometry in order to separate, identify, and quantify substances in a sample.
Technology
Gel permeation or sieve chromatography that is performed on porous gels that separate solutes on the basis of size. Smaller solutes are included within the particles of the gel matrix more frequently than larger solutes, thus affecting elution rates.
Technology
Frequently referred to simply as HPLC, this form of column chromatography is used frequently in biochemistry. The analyte is forced through a column by liquid at high pressure, which decreases the time the separated components remain on the stationary phase. Less time on the column then translates to narrower peaks in the resulting chromatogram and thence to better selectivity and sensitivity.
Technology
Affinity chromatography using monoclonal or polyclonal antibodies, or (less commonly) antigens, as the immobilized binding phase.
Technology
A type of chromatography assay in which an antibody-conjugate is passed over an immobilized antigen, giving a visual indication of positive or negative result.
Technology
A type of chromatography in which separation of a mixture is achieved by passing a sample in a stream of liquid solvent through some form of material that will provide resistance by virtue of chemical interactions between the components of the sample and the material.
Technology
LC/MS is a hyphenated technique, combining the separation power of liquid chromatography (LC), an analytical chromatographic technique for separating ions or molecules dissolved in a solvent, with the detection power of mass spectrometry(MS), a technique to separate gas phase ions according their m/z (mass to charge ratio) value. Used for drug screening, pharmacology studies, environmental analyses and forensics.
Technology
An analytical technique wherein liquid chromatography is coupled to tandem mass spectrometry in order to separate, identify, and quantify substances in a sample.
Technology
Separation of protein fractions by precipitation, chromatography, or other methods.
Technology
Mass spectrometers coupled in series. The targeted compound is selectively ionized, and its characteristic ions are separated from others in the mixture in the first mass spectrometer. The selected primary ions are then decomposed by collision, and from the resulting products the final mass analyzer selects secondary ions characteristic of the targeted compound. Tandem mass spectrometry can achieve specificities and sensitivities equivalent of those of methods such as radioimmunoassay and gas chromatography/mass spectrometry, while performing analyses in much shorter times.
