The LOENCO Model 7 0 Hi-Flax is not just another chromatograph. It is a : versatile research-instrument for those who will; hot compromise with accuracy. The Model 7 0 is available as a standard unit including dual column'programming and with a variety of optional features. Optional LOENCO detection systems can be simultan eously installed and operated in the large detector oven, adding to the system's flexibility. If flexibility, accuracy and reliability are your goals, -send for Bulletin 7 0 which de scribes this system in detail.
