Abstract
A light weight apparatus for sampling a gas mixture, especially a gas under pressure, in order to ascertain the extent of contamination in said mixture, including gaseous, liquid and solid contaminants. The apparatus includes in combination a filter means to capture a sample of the solid particulates and the vapor and a means to capture a representative sample of pressurized gas. A novel fitting in which two hypodermic needles are embedded is operatively connected to the pressurized gas at one of its ends and to a sampling tube at the other of its ends. A modified fitting is used to obtain a sample of the ambient atmosphere if this is desired.
Claims9
A sampling system for taking gas samples, vapor and solid particulates therein which includes in combination:
- a gas sample container;
- means to connect said sample container with a pressurized source of gas to be analyzed;
- a filter section operatively connected to said pressurzied gas;
- a flow measuring section operatively connected to said pressurized gas;
- and
- means connecting the sample container to the rest of the system, said means comprising a plug adapted to connect to said pressurized gas and having a minute passage through which gas to be sampled can flow into said sample container.
A fitting having one end of said fitting adapted to cooperate with a gas pumping device and a cup-shaped recess at the opposite end of said fitting adapted to receive a sampling container and two hypodermic needles embedded in said fitting with one end of each of said needles extending into said cup-shaped recess, one of said hypodermic needles also opening into the opposite end of said fitting and the other of said hypodermic needles opening to the side of said fitting.
A fitting comprising a plug having a lower end adapted to cooperate with a source of gas to be sampled:
- a cup-shaped upper end adapted to receive a sampling container;
- two hypodermic needles, one passing through said plug and extending into said cup-shaped end, the other of said needles extending into said cup-shaped end, venting before the entry end of said plug;
- and
- a traverse bore in said fitting operatively connected to said vent.
