Introducing DART-HT = 96-well format Scanning with feedback loop control and improved sample positioning
|

 |
Everyone is under pressure to get answers. We want to help! At the meeting this year you can see our new
DART-HT system, it offers high speed sampling using multi-dimension sample scanning system with improved sample positioning reliability. If you have a burning desire to reduce your cost per analysis w
e are looking for candidates for our validation program.
Interested in more rapid sample prep? Then talk to us about our
PARALLEL SPME technology for a start. We are working with
Waterloo U., and
MilliporeSigma to enable simultaneous solid phase extraction of up to 96 samples in under an hour? Start your meeting with Prof.
Pawliszyn at
9:50 AM Monday, Development of Solid Phase Microextraction (SPME) Devices for Analysis of Drugs in Biofluids via DART
.
How about getting a report of a potential unknown from your
IMS and then being able to get a mass spectrum using without changing your sample collection method? The
DART-TD
for thermal desorption from SWABs enables
direct determination of chemicals desorbed from Morpho Systems
IMS sample SWAB
in seconds per sample. Add
DART-TD
to your high resolution LC/MS or LC/MS/MS systems. Stop by booth #718 to discuss joining our
validation program.

Ready for a Nightcap?
This year
DART will be center stage in the
WATERS CORP Hospitality Suite. Check out the non-stop appearance of the
DART/QDa to learn more about our exciting partnership. For a highlight-reel of the utility of DART with mass detection click

thats right, forget the .com. Interested in really at-the-reaction monitoring. Join one of our focus groups. Stop by the booth #718 to register!
See you soon!

Rapid analysis of trace drugs and metabolites using a
thermal desorption DART-MS configuration
National Institute of Standards and Technology,
Materials Measurement Science Division, Gaithersburg, USA
The need to analyze trace narcotic samples rapidly for screening or confirmatory purposes is of increasing interest to the forensic, homeland security, and criminal justice sectors. This work presents a novel method for the detection and quantification of trace drugs and metabolites off of a swipe material using a thermal desorption direct analysis in real time mass spectrometry (TD-DART-MS) configuration. A variation on traditional DART, this configuration allows for desorption of the sample into a confined tube, completely independent of the DART source, allowing for more efficient and thermally precise analysis of material present on a swipe. Over thirty trace samples of narcotics, metabolites, and cutting agents deposited onto swipes were rapidly differentiated using this methodology. The non-optimized method led to sensitivities ranging from single nanograms to hundreds of picograms. Direct comparison to traditional DART with a subset of the samples highlighted an improvement in sensitivity by a factor of twenty to thirty and an increase in reproducibility, measuring integrated area of the base peak, sample to sample from approximately 45% RSD to less than 15% RSD. Rapid extraction-less quantification was also possible.
