This area has developed as a special discipline because it is characterized by special techniques requirements imposed by physical limitations and economic needs and unique phenomena associated with low-thermal-energy levels. Compounds that are processed within the cryogenic temperature region are sometimes called cryogens. There are only a few of these materials they are generally small relatively simple molecules and they seldom react chemically within the cryogenic region. Table lists the major cryogens along with .
