Page 9 ADDENDUM The chart recorder of the UA-6 can be set to produce charts based on cm/ml length of chart per unit vol- ume pumped instead of the traditional cm/hr (length of chart per unit time). For volume based charts, plug the square 4-pin connector on the cable (part number 60-1020-163 or 60-1020-228) into the socket labeled REMOTE CHART DRIVE on the rear panel of the UA-6.

A UA-6 has a 0.1 nm bandwidth at 254 nm and certain other wavelengths, which is excellent. A UA-6 has a 15 nm bandwidth at 280 nm and certain other wavelengths, which is only fair, so shorter pathlength cells are generally better at these wave- lengths.

UA-6 Detector Section 3 Operation 3.7.2 Flow Rate The Teledyne Isco high flow rate cell is designed to handle liquid flows up to about 3 liters/min with negligible pressure drop. Liquids with viscosities much greater than water may present difficulties at high flow rates, while most cells can handle higher flow rates of water or other non-viscous liquids if some pressure drop across the flow cell is not objectionable.

Page 46 Drift performance is directly related to the stability of the ambient temperature. The UA-6 can operate at any temperature between 0°C and 40°C without affecting drift, as long as it remains stable. Temperature changes of 1°C will cause noticeable drift at a SENSITIVITY setting of 0.002 AUFS.
