Abstract

See full text

A heat exchanger that is useful for analyzing samples, such as condensate, and methods of cooling a sample for analysis are provided as embodiments of the present invention. The heat exchanger includes an inner tube for containing cooling water and an annulus for containing steam so that heat exchange occurs between the cooling water and the steam so that condensate forms in the annulus. An external shield is attached to the heat exchanger to provide additional natural cooling and to prevent users from contacting the steam contained within the annulus.
