  2. Chromatography in blood processing - Wikipedia

    en.wikipedia.org/wiki/Chromatography_in_blood...

    Compared with the Cohn process, the albumin purity went up from about 95% to 98% using chromatography, and the yield increased from about 65% to 85%. Small percentage increases make a difference in regard to sensitive measurements like purity. There is one big drawback in using chromatography, which has to do with the economics of the process.

    en.wikipedia.org/wiki/Separation_process

    Chromatography separates dissolved substances by different interaction with (i.e., travel through) a material. High-performance liquid chromatography (HPLC) Thin-layer chromatography (TLC) Countercurrent chromatography (CCC) Droplet countercurrent chromatography (DCC) Paper chromatography; Ion chromatography; Size-exclusion chromatography (SEC)

  4. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme

  5. Isotope dilution - Wikipedia

    en.wikipedia.org/wiki/Isotope_dilution

    In a typical gas chromatography analysis, isotopic dilution can decrease the uncertainty of the measurement results from 5% to 1%. It can also be used in mass spectrometry (commonly referred to as isotopic dilution mass spectrometry or IDMS), in which the isotopic ratio can be determined with precision typically better than 0.25%.

  6. Chromatography column - Wikipedia

    en.wikipedia.org/wiki/Chromatography_column

    Chromatography columns of different types are used in both gas and liquid chromatography: Liquid chromatography: Traditional chromatography columns were made of glass. Modern columns are mostly made of borosilicate glass, acrylic glass or stainless steel. To prevent the stationary phase from leaking out of the column interior a polymer ...

  8. Paper chromatography - Wikipedia

    en.wikipedia.org/wiki/Paper_chromatography

    Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition. In paper chromatography, substances are distributed between a stationary phase and a mobile phase.

    en.wikipedia.org/wiki/Chargaff's_rules

    A diagram of DNA base pairing, demonstrating the basis for Chargaff's rules. Chargaff's rules (given by Erwin Chargaff) state that in the DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine.
