For precise partitioning use gas chromatography tubing by Superior The reason is a composite of many out standing advantages: desirable inner surface, uniform bore and size, good corrosion resistance, ease in fabricating and bending; also good heat resisting characteristics and the ability to receive a wide variety of coatings. We offer tubing for gas chromatography columns in Types 304, 316, 321 and 347 stainless steels and in 30% cupronickel. We make this tubing for capillary (Vi6 in. OD χ .010, .016 and .020 in. ID), mini ature (.020 in. OD χ .010 in. ID, .028 in. OD χ .016 in. ID, and .032 in. OD χ .020 in. ID) and packed columns i}k in. OD χ 3 /i6 in. ID). We supply it in long lengths. For other small-diameter tubing appli c a t i o n s , we p r o d u c e more than 120 analyses in sizes from .010 to % in. OD in quantities from 50 to over 1,000,000 f t .
