PURSPEC Technologies Inc., whose miniature spectrometers may improve medical diagnosis and patient compliance by reducing the time needed to analyze samples, has opened offices in the Purdue Research Park.

PURSPEC also has locations in Beijing and Shanghai.

The miniature spectrometers developed by PURSPEC can be used to identify the type and amount of chemicals present in blood and urine samples in place of conventional mass spectrometry.

"Being able to check levels at the point of care instead of sending samples to a centralized location saves valuable time and enables physicians to make a diagnosis or determine a course of treatment more quickly," said Zheng Ouyang, president and founder of PURSPEC. "The reduced time means physicians can get answers promptly and move treatment to the next level so the patient receives more expedient care, which can be critical in some circumstances."

Ouyang is an adjunct professor at Weldon School of Biomedical Engineering at Purdue and a professor at Tsinghua University in Beijing.

Ouyang said the spectrometers developed by PURSPEC have other benefits as well.

"PURSPEC spectrometers can have a tremendous impact on the level of care that a patient receives. After the doctor prescribes the standard dosage for the medication, the pharmacist administers the dosage and waits 30 minutes for test results. Once levels are tested to ensure that the patient response is optimal, dosage can be adjusted if needed," he said.
