Case

A university school of pharmacy uses Shanghai Instruments UV spectrophotometer to improve drug analysis efficiency

In the analysis of drug ingredients, the pharmacy school of a certain 985 university selected the UV-2600 UV-visible spectrophotometer produced by Shanghai Instruments Scientific Instruments. The instrument has a high-precision dual-beam optical system with a wavelength accuracy of ±0.3nm and a spectral scanning speed of 3000nm/min. After use, the sample analysis time was shortened from the original 1 hour to 20 minutes, the detection limit was reduced to 0.5μg/mL, and the data repeatability was better than 0.5%. The college said that Shanghai Instruments’ after-sales service responded promptly and provided regular calibration and software upgrades, ensuring the smooth progress of scientific research projects.

A sewage treatment plant applies Shanghai Sanxin online pH meter to realize real-time water quality monitoring

A sewage treatment plant in East China with a daily processing capacity of 50,000 tons installed 6 Shanghai Sanxin SX-620 online pH meters in the biochemical treatment stage to replace the original imported brand instruments. This pH meter uses pollution-resistant electrodes, automatic temperature compensation, measurement range 0-14pH, accuracy ±0.05pH, and response time <15 seconds. After half a year of operation, the accuracy of real-time pH monitoring has increased to 99.7%, the failure rate has been reduced by 70%, and the price of a single unit is only 1/3 of imported products. The manufacturer stated that Sanxin’s local technical support team can arrive at the site within 4 hours, which greatly reduces operation and maintenance costs.
