A fully automated system with an optical immersion probe (OIP) for high-precision spectrophotometric measurements

Online determination of sulfide using an optical immersion probe combined with headspace liquid-phase microextraction

“…Compared to measuring absorbance in a cuvette, the use of an optical probe speeds up the analysis; since the sample does not need to be transferred to the cuvette, and the determination precision is increased. [15][16][17] Optical probe can be directly immersed in the plastic vial in headspace mode, which solves the problem of droplet stability and limitations in the volume of the acceptor phase.…”
