Comment:
Sample comment code: Threshold pressures are not accurate because release of small volumes of gas could not be controlled at high pressure. (+) = potential small addition; (++) = potential large addition; (1) = PCS not warmed; minimum total gas volume; (2) = PCS not maintained at 0°C, 0.1 MPa for a long time; minimum volumes; (3) = port clog; (4) = a small but unknown quantity of gas was lost from Core 164-995A-48P; (5) = gas released from this core rapidly under warming conditions; (6) = temperature greater than 0°C when core was first opened.
