Having collected the data, a calibration curve should be<br />
plotted. Since amphetamine is frequently synthesized in dirty<br />
apparatus in ‘cl<strong>and</strong>estine cl<strong>and</strong>estine’ laboratories, it may not be possible<br />
to determine which salt form of the drug is present. The<br />
st<strong>and</strong>ard is generally supplied as the sulfate form, of the<br />
general formula (amphetamine sulfate). This means that for<br />
every gram of amphetamine sulfate, 73% will be present as the<br />
amphetamine free base. The calibration curve should be<br />
plotted as (UV detector) response against concentration of<br />
amphetamine free base<br />
