Abstract: A pressure cell for sum frequency generation spectroscopy includes: a metal pressure chamber; a heating stage that heats a liquid sample; an ultrasonic stage that emulsifies the liquid sample; a chamber pump that pressurizes an interior of the metal pressure chamber; and a controller that controls the chamber pump, the ultrasonic stage, and the heating stage to control a pressure of the interior of the metal pressure chamber, an emulsification of the liquid sample, and a temperature of the liquid sample, respectively. The metal pressure chamber includes: a liquid sample holder that retains the liquid sample; a removable lid that seals against a base; a window in the removable lid; a sample inlet that flows the liquid sample from an exterior of the metal pressure chamber to the liquid sample holder at a predetermined flow rate; and a sample outlet.

Abstract: The invention relates to an apparatus (100) for collecting dust samples. The apparatus comprises a piston (102) and a cylinder (110) for holding the piston with a body having a hole (108) extending through the body. The cylinder (110) has a first end (112), which is open, the first end of the cylinder being slanted such that underside (130) of the cylinder extends farther than upper side (132). A mechanism (114) moves the piston between inward and outward positions. The apparatus gathers dust flowing past the piston into the hole of the piston when the piston is in the outward position and moves the gathered dust by moving the piston into the inward position. An input feed (116) is configured to spread fluid through the hole filled with dust to flush the dust to an output feed (118).
