Detection Modes

Peak Height, Integration, and Analog (Rate).

Blank Subtract

Three levels of Blank Subtract with 10 turn dial for fine adjustment.

Digital Panel Meter

Indicates intensity of light detected by PM tube. Easy-to-read 3 1/2 digit LED display.

Power requirements

105-130, or 200-260 volts, 50 / 60 Hz, 25 watts.

MODEL SPECIFICATIONS/CATALOG NUMBERS

(Test tubes) 10 x 75mm or 6 x 50 cuvettes in easily-changed adapter.

(Flow cell) 70ul, 1 meter flow cell with industry standard 1/16" cone ferrule stainless steel HPLC fittings for inlet and outlet. Used with external mixers and reactors.

(Flow cell with mixing tee) 70ul, 1 meter flow cell with an integral mixing tee. The mixing tee is exposed directly to the photodetector. Used with very fast reactions where delay between mixing and light detection is undesirable.
