To effectively enhance the professional skills of the company’s laboratory analysts, IGSR recently held a practical skills competition for laboratory analysts. All laboratory employees competed to fully demonstrate their solid professional knowledge and proficient practical abilities.

The competition focused on core daily testing work and set up two major assessment items: the standardization of 0.1 mol/L hydrochloric acid standard solution, and the 5-fold dilution of a 50-ppm ammonia nitrogen standard solution followed by detection of the ammonia nitrogen value. The assessment emphasized employees' operational standardization, experimental accuracy, and rigor in data processing. The competition site was tense and orderly, with participants fully focused. From the cleaning and rinsing of glassware and precise weighing on the analytical balance to the keen judgment of titration endpoints and the correct zeroing and colorimetric measurement of the spectrophotometer, every step strictly followed operational standards. This competition not only provided a platform for employees to exchange skills but also promoted mutual learning and improvement through competition-driven practice and enhancement, building a solid guarantee for the company's product quality.
