The phrase "assessed using gas" is correct and usable in written English.
It can be used in contexts where a process or measurement is evaluated with the help of gas, such as in scientific experiments or assessments.
Example: "The air quality was assessed using gas chromatography to determine the concentration of pollutants."
Alternatives: "evaluated with gas" or "measured using gas".
Salivary MHPG was assessed using gas chromatography mass spectrometry (Hitachi-M80B, Hitachi, Japan) at Kurume University, Japan, as described previously (Yajima et al., 2001).
Isotopic enrichments in tissue fluid were assessed using gas chromatography-mass spectrometry (Hewlett-Packard 5971A; Hewlett-Packard Co., Palo Alto, CA, USA) and were used as precursor pool enrichment for the calculations of the fractional synthesis rates (FSR).
Changes in penile circumference, measured using a gauge placed around the shaft of the penis, or changes in penile volume (assessed using gas displacement in a sealed cylinder placed over the penis) are the most commonly used methods in sexual arousal research.
Isotopic enrichment was assessed using gas-chromatography mass spectrometry with selected ion monitoring of derivatized samples.
The syringe precision and accuracy of smoke dose generated by the RM20S was assessed using a methane gas standard and resulted in a repeatability error of ≤9%.
Oxygen consumption (VO2) and carbon dioxide production (VCO2) during exercise were assessed using an online gas analyser (Oxycon Pro, Jaeger, Germany).
Overall functioning was assessed using the Global Assessment Scale (GAS) [ 24].
Arterial blood pH, oxygen and carbon dioxide partial pressures (pO2, pCO2); oxygen saturation; base excess (BE); hemoglobin concentration; hematocrit; electrolytes (Na+, K+, Cl-, Ca2+); metabolic parameters (lactate and glucose concentrations); and osmolality were assessed using a blood gas analyzer (ABL 715; Radiometer, Copenhagen, Denmark).
