Frequently Asked Questions

“Extraction in Seconds”, DPX tips are fast! Depending on the application, our customers typically find that extraction time is significantly reduced when compared to traditional SPE. Most significantly, DPX tips are designed to work seamlessly on robotic liquid handlers, unlike conventional SPE.

While “dilute and shoot” methods are often perceived as “inexpensive” and “rapid”, our customers frequently tell us that they have had to purchase high-end ultra-sensitive instrumentation in order to achieve the desired analytical outcomes. With strategic emphasis on sample preparation (i.e. “the front end”), significantly higher costs associated with more expensive LC-MS/MS instrumentation may be unnecessary. DPX tips produce cleaner extracts resulting in lower solvent volumes and waste generation. LC column life is extended. Cleaner extracts also lead to less LC-MS/MS maintenance, fewer repeat sample injections and reduced data analysis time.

DPX tips are routinely used with whole blood, serum, urine, oral fluid and solid biological specimens in a variety of clinical laboratory medicine and forensic toxicology applications. In addition, DPX tips are being used in food safety analyses, to include fruits, vegetables, dairy and meat products.
