Thermometer ions for matrix-enhanced laser desorption/ionization internal energy calibration

Internal energy of ions generated by matrix-assisted laser desorption/ionization.

To provide an objective measure of the correlation between the internal energy content of ions generated by matrix-assisted laser desorption/ionization (MALDI) and the matrix properties, a series of well-characterized benzyl-substituted benzylpyridinium salts were used as thermometer molecules (TMs). To determine the internal energy variations of analyte ions, the survival yields of TM molecula...

Automated System for Thermometer Calibration

Calibration of thermometers is timeconsuming process that requires short-term temperature stability during multiple measurements at given temperature points. In most laboratories, thermometer calibration process is not automated, requiring the presence of the laboratory assistant during the calibration and for the subsequent calculation of the measurement uncertainty. In this paper, an automate...

The Nist Industrial Thermometer Calibration Laboratory

The NIST Industrial Thermometer Calibration (ITC) Laboratory provides calibrations of industrial thermometers over the range from –196 °C to 550 °C. The different types of thermometers include liquid-in-glass (LiG), thermistors, thermocouples (<200 °C), and industrial platinum resistance thermometers (IPRTs). Calibrations are performed by both comparison with a standard platinum resistance ther...
