A representative embodiment is directed to a fitting for fluidically coupling a GC column to another structure. The fitting comprises: a first end configured to receive a ferrule having a tubular element disposed therein, the tubular element being oriented in a first direction; and a second end fluidically connected to the first end and having an opening to provide a fluid from the tubular element in a second direction that is different from the first direction. The second end comprises a substantially planar portion, and the planar portion is configured to make a substantially gas impermeable seal with another element of a GC system.

A fitting as claimed in claim 1, wherein the ferrule is press-fit into the first end of the fitting. 3. A fitting as claimed in claim 1, wherein the second direction is substantially perpendicular to the first direction. 4. A fitting as claimed in claim 3, wherein the fitting comprises a first material and a coating disposed over the planar portion. 5. A fitting as claimed in claim 4, wherein the coating fosters the substantially gas impermeable seal. 6. A fitting as claimed in claim 1, wherein the tubular element extends beyond an end of the ferrule. 7. A fitting as claimed in claim 1, further comprising a pliable layer over the substantially planar portion. 8. A fitting as claimed in claim 1, wherein the fitting further comprises: a cavity at the first end receiving the ferrule and oriented, in the first direction;a first channel oriented in the first direction and fluidly connected to the first end;a second channel oriented in the second direction and fluidly connected to the first channel and the opening; anda pliable layer disposed around the opening. 9. An apparatus comprising the fitting of claim 1, and comprising a GC detector connection, or a GC inlet connection, or GC flowpath device, as the other structure fluidly coupled to the GC column. 10. An apparatus according to claim 9, comprising the fitting of claim 1 and another element of a GC system, wherein the substantially planar surface of the fitting makes a substantially gas impermeable seal with the other element of the GC system. 11. An apparatus for fluidically coupling a gas chromatography (GC) column to another structure, the apparatus comprising: a first fitting, comprising: a first end that receives a ferrule having a tubular element disposed therein, the tubular element being oriented in a first direction a second end fluidically connected to the first end, the second end comprising a first substantially planar portion, the second end comprising an opening oriented in a second direction that is substantially perpendicular to the first direction; anda second fitting, comprising: a first end and a second end fluidically connected to the first end, the second end of the second fitting comprising a second substantially planar portion, wherein the first substantially planar portion of the first fitting makes a substantially gas impermeable face-seal with the second substantially planar portion of the second fitting. 12. An apparatus as claimed in claim 11, wherein the ferrule is a first ferrule, the tubular element is a first tubular element, and the second fitting receives a second ferrule having a second tubular element disposed therein, the first and second tubular elements being oriented in the first direction. 13. An apparatus as claimed in claim 12, wherein the first ferrule is press-fit into the first end of the fitting. 14. An apparatus as claimed in claim 12, wherein the first fitting comprises a first material and a coating disposed over the first substantially planar portion. 15. An apparatus as claimed in claim 14, wherein the coating fosters the substantially gas impermeable seal. 16. The apparatus of claim 11, wherein the tubular element is a GC capillary column and the first end of the second fitting is fluidically coupled to another element of a GC system. 17. An apparatus for fluidically coupling a gas chromatography (GC) column to another structure, the apparatus comprising: a body comprising: a first element; a second element, a third element and a fourth element, and a first channel and a second channel, wherein the third element and the fourth element each comprise a substantially planar portion and an opening in a substantially planar portion, andwherein the first channel connects the first and third elements, and the second channel connects the second and fourth elements. 18. An apparatus as claimed in claim 17, further comprising a GC column, wherein the GC column is connected between the first element and the second element.
