Discover the LDTD

A breakdown of the LDTD process:

  1. Low volume (up to 10µl) of extracted liquid sample
    deposited onto LazWell™ well surface
  2. Sample is quick dried
  3. Indirect thermal desorption of sample using precisely controlled Laser Diode
  4. The desorbed neutrals are transported using compressed Air
  5. Ionization occurs using Atmospheric Pressure Chemical Reaction (APCI) without solvent
  6. Ions are formed and introduced into MS for detection

Application Fields

In early drug discovery, a drug candidate (NCE) needs to be characterized for critical go or no go decision making through Absorption, Distribution, Metabolism, Excretion and Toxicology (ADMET) evaluation.

Our technology increases the analytical throughput for such analysis and provides scientists with increased data turnaround time for faster project decisions.


Toxicology and Forensic testing requires fast turnaround times with accurate results. What if you could perform Drug of Abuse or PDM testing in less than 4 seconds per sample? This is exactly what the LDTD does on a daily basis with millions of samples having been analyzed since it was first introduced to the field in 2008.

Drug testing is normally performed in urine and oral fluids, but other matrices such as hair or blood can be quickly analyzed using the LDTD ionization source. Ultra-Fast screening combined with accurate quantification results will increase your laboratory’s productivity.


Measurement of drugs and their metabolites in biological fluids is the foundation of both therapeutic drug monitoring (TDM) and toxicology. Each discipline relies on accurate identification and quantification for these measurements to be useful. Immunosuppressant testing, Vitamin D and Testosterone are a few of the most common tests conducted.



In a world where quality control and health issues are so important to our society, ultra-fast methods for characterization of food contaminants are needed.

The robustness of the LDTD and its speed allow for detection of environmental or food contaminants without extensive sample preparation even in more complex matrices.




Our patented LazWell™ plates work exclusively with the LDTD system to provide accurate and reproducible results at incredible speed.

  • The LazWell96 well format is designed specifically for use with the LDTD-960 model and can accommodate sample volumes of up to 10µl.
  • The LazWell384 plate format fits on the LDTD-3840 system and offers a higher sample throughput for specialized applications requiring low volumes – maximum 2 µl of sample.

Are you ready to see the Luxon in action?
Take the next step with our On-Site Evaluation!

Based on availability of demo instruments and on a case by case basis, we can send the Luxon Ion Source to your facility and a Phytronix Application Scientist will perform the system installation, provide training, and assist you for one (1) week in your method development. Following this initial week of method development, the LDTD Ion Source is on loan for up to three (3) additional weeks for your evaluation. There is no charge for labor, installation, training, method assistance or the additional three weeks of use. The only charge is for the LazWell™ plates used during the evaluation period. All previous models (LDTD)  can be made available for your on-site evaluation.
