1.1 This guide describes some standard procedures applicable to the analysis of phencyclidine and its analogues using microcrystal tests (1-8).

1.2 These procedures are applicable to phencyclidme and its analogues which are present in solid dosage form or in a liquid form. They are not typically applicable to the analysis of phencyclidine and its analogues in biological samples.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard cannot replace knowledge, skill, or ability acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The technique produces a chemical-precipitation reaction between the phencyclidine or its analogues and the precipitating reagent. The habit and the aggregation of the crystals formed may be used to distinguish phencyclidine or its analogues from other drugs.

The technique can be utilized on phencyclidine or its analogues present in either the salt or free base form.

The technique does not distinguish between salt and free base forms.
