It was originally used about 90 years ago to separate different color pigments in plants, hence the root "chroma" which is Greek for "color". ncaa and steroids Steroid forums. Once a solution or gas is produced of the desired sample, the different chemicals in the sample will have different absorption characteristics in a solid or liquid phase medium. You may have heard or read the term "HPLC" when talking about testing the purity of supplements. HPLC refers to high-pressure liquid chromatography. ncaa and steroids Steroid withdrawal. With HPLC solutions are pumped through a column under very high pressure (3000/in2 or more). In this case researchers are using gas chromatography (GC). It is the same method used to test emissions on cars. ncaa and steroids Anabolic diet results. Mass spectrometry is another commonly used method of separating atomic sized particles in a gas based on weight. In mass spectrometry, a beam of gaseous ions is deflected in a magnetic field toward a collector plate. Lighter ions are deflected more than heavy ones. By comparing the accelerating voltages required to deflect the two ions to the same point on the collector plate, it is possible to determine the relative masses of the ions. I'm sure most of you aren't as interested in the technology as you are in the consequences of using it in drug testing. In this case researchers are using hair to determine what anabolics are or were taken. Each hair on your body consists of a shaft and a root. The shaft consists of three principle parts. The inner medulla is composed of polyhedral cells containing granules of eleidin and air spaces. The middle cortex forms the major part of the shaft and consists of elongated cells that contain pigment granules in dark hair but mostly air in white hair. The cuticle of the hair, the outermost layer, consists of a single layer of thin, flat, scalelike cells that are most heavily keratinized. It is these cells that contain metabolites of whatever anabolics you have been taking. The thing about hair is that it provides the investigator with a rather long history of the subjects drug use. Much longer than urine or blood.
