INTRODUCTION

　　Direct sample analysis is possible via an Atmospheric Solids Analysis Probe (ASAP®) combined with atmospheric pressure chemical ionization (APCI) on a compact mass spectrometer (CMS) (Figure 1 and 2). This technique allows for the rapid investigation (<30 sec) of material suspected of containing THC/cannabinoids (example chemical structures and molecular weights shown in Figure 3).

　　METHOD

　　Touch the closed end of the glass melting point capillary to the sample material, and then insert the direct analysis probe into the mass spectrometer for analysis. Obtain results in seconds.
