Serpentine interface tubes

Katz and Scott [42] solved this problem by the use of low dispersion serpentine tubing as the interface between the exit from the UV detector of the liquid chromatograph and the spectrometer. A diagram of their interface is shown in figure 43. The principle of low dispersion tubing has already been discussed and it is sufficient to say that the outer interface tube was 49 cm long, 0.25 cm I.D. and merely protected the serpentine tube contained inside. The inner serpentine tube had a peak-to-peak amplitude of 1 mm. An example of the chromatograms obtained from a blood sample monitored by both a UV... 

The low dispersion serpentine tube developed by Katz et e> OO) was an alternative approach to the coiled tube and was designed to increase secondary flow by actually reversing the direction of flow at each serpentine bend. A diagram of a serpentine tube is shown in figure 3. In fact, the serpentine tubing shown in figure 3 was designed to be an interface...
