Preparation of aqueous mobile phase is the most critical step in reversed-phase chromatography (RPC) method development for ionic analytes. This includes consideration of the affects of pH on analyte retention, type of buffer to use, and its concentration, solubility in the organic modifier and its affect on detection, among other considerations.

This course is a broad introduction to a host of sensor technologies, illustrated by applications drawn from human-computer interfaces and ubiquitous computing. After extensively reviewing electronics for sensor signal conditioning, the lectures cover the principles and operation of a variety of sensor architectures and modalities, including pressure, strain, displacement, proximity, thermal ...

Each listed percentage volume represents 100% of the Lower Explosive Limit for that gas or vapour, that is the point at which the gas is just capable of ignition.So flammable gas detectors must be calibrated to be best response for the flammable gas hazard in question and must measure in the region from no gas (zero) to the point the gas is just flammable, or 100% LEL.

The normal concentration of oxygen in the atmosphere is approximately 20.9% volume. Oxygen levels can be dangerous if they are too low (oxygen depletion) or too high (oxygen enrichment). The same oxygen monitor will alert to both enrichment and depletion. Oxygen Depletion: In the absence of adequate ventilation the level of oxygen can be reduced surprisingly quickly […]

Description. The FP-31 is a highly sensitive portable gas detector specific for formaldehyde detection. It uses a photoelectric photometry method which utilizes colorimetric tablets for detection.

The water vapor in the sample activates the scrubbing media to produce phosphoric acid. The phosphoric acid then reacts with the ammonia in an acid-base neutralization reaction producing a phosphate of ammonia. This compound is a solid even at elevated temperatures, and deposits immediately within the ammonia scrubber as a visible salt residue.
