When measuring the S.G. of high gas samples, do you recommend water quenching the sample from an elevated temperature?
A brief water quench is not likely to pull water into the cavities exposed to the surface as long as the temperature of the sample is hot to the touch when removed from the quench. There is probably more risk in the sample gaining moisture during the “weigh-in-water” portion of the evaluation. However, if the immersion is done quickly and the measurement taken as soon as the reading stabilizes, the amount of error introduced is normally small. A correction can be made manually by reweighing the sample after removal from the water, and subtracting the gain in weight from the original measurement. A manual re-calculation of the S. G., as described in the Instruction Manual, will produce the corrected result.
