To demonstrate DART's ability to detect explosives in complex matrices, a sample of pond water was spiked with mixture of 3ppm each of various explosives. A 2mm diameter glass rod was dipped into the water and after the sample dried onto the tube it wa...

Negative Ion mass spectrum of Gunshot Residue (GSR) shows significant ions related to nitroglycerin and other materials.


Gunshot Residue: Positive Ions
Positive ion DART spectrum yields numerous ions related to gunpowder i...

Rapid determination of formulations can be accomplished by using the DART SVP TLC paper holder to scan the sample after it has been sprayed or deposited on filter paper. In this experiment we expelled a single spray from two different inhalers onto the...

So called matrix effects often dictate that samples be analyzed by LC/MS since their presence with analyte leads to inefficient ionization or formation of adducts. The effect of various solvents on DART efficiency is show here using the common standard...

Simplify reaction monitoring over time with instant feedback. Here we compare LC/MS data showing the relative concentration of the precursor and product over time vs. results obtained without the LC separation using DART. The distribution of ions in th...
