摘要： A method and apparatus for determining a physical property of a gas in a confined space. Gas of known volume, pressure and temperature is placed in communication with a confined space containing gas at known pressure to determine the volume of gas in the confined space using computations based on the gas laws. Alternatively, gas of known pressure, volume, and temperature may be placed in communication with a confined space containing gas at known volume to determine the pressure of gas in the confined space prior to communication with the gas of known properties. Gas volume determinations are useful, for example, to perform rheological characterizations of liquid samples.

摘要： Apparatus for accurately metering liquid flow based on the injection of a brief heat pulse into the flowing stream, e.g., via a miniature thermistor, and detection of an electronic time derivative of temperature downstream with, e.g., a second microprobe thermistor. This detection triggers a subsequent heat pulse and the cycle repeats, with pulse total corresponding to elapsed liquid throughput, and pulse frequency to flow rate.

摘要： Analytical method based on converting an acid or base species to water or absorbing the acid species whereby the species of interest is no longer responsive to a detector. Interfering salt(s) is simultaneously converted to a detectable acid or hydroxide derivative(s) in whole or in part. The species of interest is determined indirectly by subtracting the response of the salt derivative (which is proportional to the original salt) from a pre-derivatization response which is proportional to the salt plus base or salt plus acid.
