If your theory is true why would the size of the pill make a difference and the size of a crystal not make a difference?
Why if small pill and less filler is the key. How come MDMA crystal takes longer to come up 45mins-hour if your theory were correct the MDMA crystal would come up quicker because it has no filler or binder at all.
5.2.4.2 Gas Chromatography
Gas chromatography (GC) is a documentable chromatography form that can be used in lieu of TLC. It is not a specific confirmatory test for controlled substances. However, dual-column techniques and the evaluation of alkaloid
peak patterns can be used for identification purposes. The GC is also used as a separation device for confirmatory examinations, such as MS and Fourier transform IR spectroscopy (FTIR). The GC separates compounds by their size, shape, and reactivity with the chemical coating of the GC column, in a manner similar to rocks flowing down a river. The carrier gas acts as the water, and the column coating acts as the riverbed. The small molecules travel through the chromatographic column more rapidly than larger molecules. Their shapes and their reactivities with the column’s coating separate molecules of the same size.
Chromatograms from GCs are used to identify unknowns based on the retention time or relative retention time of a peak under certain operating conditions. The retention time (Rt) is the time it takes a compound to travel from the injection port of the GC to the detector. The relative retention time (RRt) is the ratio of the retention time of the substance to the retention time of an internal standard placed into the sample.
5.2.4.3 Mass Spectroscopy
Mass spectroscopy (MS) is the workhorse instrument used by the forensic chemist. It uses the pattern of molecular pieces (ions) produced when a molecule breaks apart after it is exposed to a beam of electrons as a means of identification. The resulting characteristic pattern is called the mass spectrum. It is considered one of a compound’s chemical fingerprints. The mass spectrometer exposes the compound under analysis to a beam of high-energy electrons that shatters the molecules. The mass spectrometer then sorts and counts the resulting pieces (ions) and produces a pattern, the mass spectrum. When the energy of the electron beam remains constant, the molecule will produce the same mass spectrum, which is considered one of the compound’s chemical fingerprints.

I cant figure out if GC/MS is an all in one type of test or two independant tests.
I am no GC/MS expert but looks to me like a solution isnt creaated in either test. I only make an educated guess.
I know one thing its not a simple piece of equipment. You have to be well trained to get decent and accurate results.
One thought is we have always assumed the likes of ecstasydata.org to be accurate. Maybe some of those impurities might be user errors?
I think you work the ratios out using the peak heights as indication of relative strength of a particular compound.
Different compounds produce alternative spikes.
This document we are looking at has the bit about salts in it
I have added another book to the collection "Handbook of Industrial Crystalization" Everything you need to know when crystalizing MDMA on an industrial scale lol.
Like with GC/MS its another highly complex topic. An MDMA crystal can varie in size, can contain a percentage of impurity, contain a percentage of H20, contain a percentage of O2. In some circumstances you can crystalize isomers, you can even add adulterant. Do you think none of these factors will have any affect on the MDMA high?
