摘要：

A stopped-flow photometer is described which is simple enough for teaching applications yet sufficiently versatile to serve as a nucleus for a research instrument. The rapid mixing device employs small sample volumes (typically 20 μl of each reactant) and features a mixing time of 4 milliseconds, a pneumatic drive mechanism, and temperature control for the reactants. Rapid reactions can be monitored by changes in transmittance or fluorescence or by measuring simultaneous changes in transmittance and fluorescence. A photometric system with all solidstate electronic components is described along with an oscilloscope triggering circuit. © 1969.
