Claim 9:
10. The method of changing from a first chromatography cartridge coupled to a chromatography system to a second chromatography cartridge of claim 9,
wherein the cartridge adapter further comprises a coupling retainer comprising:
a) a keyway aperture comprising:
b) a coupling aperture;
c) a retainer slot comprising two parallel slot sides;
wherein both the first interchangeable coupling component and the second interchangeable coupling component have a retainer portion extending from the cartridge portion to a retainer end and having a pair of opposing planar sides configured between the cartridge portion and said retainer end; and
wherein the retainer portion of both the first interchangeable coupling component and the second interchangeable coupling component are configured for insertion through the coupling aperture and configured to be retained in said keyway aperture with the retainer slot configured around the pair of opposing planar sides;

wherein detaching the first interchangeable coupling component from the chromatography system comprises moving the coupling retainer to align the retainer portion with the coupling aperture to detach the first interchangeable coupling component from the coupling retainer; and
wherein attaching the second interchangeable coupling component to the chromatography system comprises inserting the retainer portion of the first interchangeable coupling component through the coupling aperture of the coupling retainer and moving the coupling retainer to configure the retainer slot around the pair of opposing planar sides of the second interchangeable coupling component.
