"Then, during the night, the leaves act as cold traps.

The most efficient systems also have a cold trap on the pump exhaust.

Such craters are cold traps that contain a fossil record of the early solar system.

It may also prove possible to extract hydrogen from the cold traps at the poles of the Moon.

It is named for its resemblance to a finger as is a type of cold trap.

Earth's upper atmosphere is a "cold trap" that prevents the water from escaping the planet.

Other volatiles containing carbon and nitrogen were found in the same cold trap as ice.

In this function, they are called a cryotrap or cold trap, even though the physical mechanism is the same as for a cryopump.

Often cold traps and baffles are used to minimize backstreaming, although this results in some loss of pumping ability.

The most important principle of all building constructions was the lowered entrance tunnel, which served as a windscreen and cold trap.

Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying.

Caves acted as cold traps in winter.

The cold trap within Faustini was identified as having a high concentration of hydrogen, relative to the norm for the lunar surface.

It is used in cold traps for certain laboratory equipment and to cool infrared detectors or X-ray detectors.

An explosion can occur due to the common use of liquid nitrogen in the cold trap, used to protect the vacuum pump from solvents.

Cigarette-smoke condensates are collected by passing smoke through cold traps and recovering the retained material.

Cold traps can also be used for experiments involving vacuum lines such as small-scale very low temperature distillations/condensations.

The separated ions would be captured by a linear array of cold traps to provide reservoirs of each element.

When performed on a larger scale, this technique is called freeze-drying, and the cold trap is referred to as the condenser.

Air flows continually through the instrument, after having first been dried in a cold trap where the water vapor freezes out as ice on the walls.

The condensate in the cold trap consists of carbon dioxide, nitrous oxide, and residual water vapor.

Two liquid nitrogen cold traps connected to the manifold are used for CO2 collection when the sample gas is extracted from the large volume.

In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid.

Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapours will backstream into the cavity.
