Abstract
A chromatograph having removable modular analysis units fitting into a chamber within the chromatograph housing, each unit including a column, sample introduction portion and detector. Each modular unit includes a block of thermally conductive material which encloses substantial portions of the sample introduction means and detector and is provided with an exposed surface adapted to contact heating means contained in the chromatograph housing.
Claims9
A chromatograph comprising a housing having walls defining a column chamber;
- a plurality of blocks constituting at least a portion of said housing walls so that said blocks are selectively detachable from said housing wall portion, at least one of said blocks carrying thereon a sample introducing portion, a column and a detector so as to form an analysis unit and including an inner block of thermally conductive material enclosing substantial portions of said sample introducing portion and said detector means;
- means for supplying a carrier fluid to said sample introducing portion;
- and means for heating said inner block, said heating means contained in said housing and having an exposed surface, said exposed surface adapted to contact a corrsponding exposed surface of said inner block of thermally conductive material whereby heat is transferred from said heating means to said inner block when said blocks are attached to said housing.
