I say- let’s just play baseball. Let’s just gather around the tv with our family and root for the home team. Let’s cherish that beloved crack of the bat and the smell of hot dogs, popcorn and beer in the air. Let’s rise to our feet when our favorite player hits a fast ball deep, and cheer wildly as it goes into the stands, becoming a souvenir for a lucky fan. Let’s just love the game for what it is, what it always has been, America’s favorite game. If a player can deal with the weight of cheating, and the many health risks of using performance enhancing drugs, then that’s their prerogative. Let’s not let the steroid era cast a dark shadow on this wonderful sport. Let’s continue to wait, and hopefully one day very very soon, steroids in baseball will be going, going, GONE!
Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more  or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram.  [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography .  : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity.
