Atomic absorption spectrometers (AAS) measure the concentration of atoms in a sample in the parts-per-billion range based on their ability to absorb light at a specific wavelength. Most samples analyzed by AAS are liquid samples, and solid samples... Read More

Cryopreservation is the process of freezing cell cultures and storing them at extremely low temperatures. During that process, cultured cells are mixed with a cryo-protective solution and added to labeled storage vials, which are then cooled to ... Read More

Humans and nature can pollute the environment, and our health often depends on tracking and analyzing the toxic compounds. Read More

The job keeps getting more complicated for forensic scientists. “Over the past 15 years,” says Thomas J. Gluodenis, forensic and forensic toxicology marketing manager at Agilent Technologies (Santa Clara, Calif.), “there’s been remarkable growth in ... Read More

As clinicians, scientists and technologists deal with an extensive variety of samples for more types of analysis, the handling process takes on an increasingly important role. Read More

“In an ideal world, spectrophotometers would be capable of measuring the entire electromagnetic spectrum on a single instrument platform, generating a variety of types of information from the sample,” says Ian Robertson, IR/NIR applications ... Read More

To analyze trace elements—metals and nonmetals— in a sample, scientists often turn to inductively coupled plasma/mass spectrometry (ICP/MS). Read More
