Researchers from the University of New Mexico will study a special sample retrieved from what is known as a
cold trap. The region from which the sample was collected from was cold enough for water to remain in a frozen state.

cold trap, a diaphragm pump and a vacuum gauge in a single, compact unit.
One of nitrogen's roles on Earth is to help form a low-temperature layer in the atmosphere that water can't get past, called a
cold trap. On a planet without nitrogen gas, Wordsworth says, water would drift to a height where the planet's atmosphere would no longer shield it from UV radiation from the planet's sun.

First, the gaseous samples loaded on the sorbent tube were thermally desorbed and passed through the
cold trap unit of the TD at a preconcentration of 5[degrees]C.
This allows operation without any
cold trap, and thus reduces the total cost of ownership.
Included in the unit is the Concentrator and a -50degC
Cold Trap to help protect the vacuum pump from corrosive effects of vapors and fumes as they evaporate from the samples.
Products were continuously passed through two traps, one maintained at 100[degrees]C (hot trap) and the other at 0[degrees]C (
cold trap).
