Iranian Knowledge-Based Firm Makes Device for Desolvation of Samples with Inert Gases
“This device is special for blowing inert gases to the sample under controlled temperature, which somehow desolvates it for sample preparation. First, the sample in the form of vials is placed inside the spaces built into the device, and the device starts to heat up from the bottom, and its temperature can be adjusted with the thermometer mounted on the device,” said Ayyoub Khoshnamvand, the director of the company’s design and production department.
“After heating, an inert gas inlet like nitrogen and air enters the outlet. Any type of inert gas that does not affect the sample can be used in this device; then, these inert gases are blown into the sample with steel needles that can be washed with all solvents, and desolvation is completed, and the solvent is either dried or thrown out,” he explained.
Noting that the samples which are placed inside the device are subjected to desolvation depending on their specialized and applied field, Khoshnamvand said, “For instance, in forensic medicine, if they are going to separate the biological sample of blood and determine what drug the person has used, they can use this device.”
When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job.
As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs, plus others.
