Abstract: A pumping system which converts a source of gas under pressure to hydraulic fluid under pressure. The system includes three free floating pistons (P 1 ,P 2 ,P 3 ) coupled through control valves (V 1 ,V 2 ,V 3 ) to the pressurized gas source on one side and through appropriate check valves to hydraulic fluid on the other side (P 4 ,P 5 ,P 6 ). The pistons are reciprocated within respective cylinders by application of the pressurized gas to one side thereof and by application of the return pressure of the hydraulic fluid to the other side thereof. Appropriate porting on the gas side of the pistons sequentially applies the gas under pressure to the three pistons to synchronize reciprocation of them so as to provide a continuous flow of fluid under pressure, upon demand, to a load.

Abstract: It has been a problem to find alternatives to agarose as a support material for affinity chromatography. It has now been found that a polysaccharide having pendant or terminal D-galactose residues can, on the one hand, be immobilised and on the other hand activated enzymically by D-galactose oxidase to form aldehyde groups, which are then reacted with a primary or secondary amino group of a ligand, for example an immunoglobulin. Immobilisation is by cross-linking or by a preceding, partial oxidation of the D-galactose residues to link the polysaccharide to a matrix through an amino group, whereby the D-galactose residues are used to perform two different functions. 
     The invention includes the support material per se, the polysaccharide, preferably a D-galacto-D-mannan, having pendant or terminal groups of formula
     (G = a D-galactose residue, LIG = a ligand residue, R = H or R and LIG together represent a residue of the same ligand molecule), its preparation and its use in the affinity chromatography of a binding partner for the ligand.
