VicoMeter at the Customer Site

For on-site verification, since no 0.5 μL imported syringe was available at the time, a 2 μL pure-water test was performed directly to avoid experimental deviation. The measurement returned 2023.65 μg, and the customer's own operation returned 2072.99 μg — the instrument passed. The customer's sample was high-concentration acrylic acid, with a reference water content of 0.05% from earlier data, tested from a bottled sample dated November 16. After repeated hands-on measurements by the engineer and the customer, the water content read 0.069% with good stability and little variation across injection volumes; the customer understood that the long storage time may have raised the moisture slightly.

Dr. Wei's Classroom

Acrylic acid is used in resin manufacture, synthetic rubber latex production, and many other fields. Acrylic fibers are overwhelmingly used for clothing, decorative products, artificial fur, and other textiles, with little used elsewhere. Industrially, acrylic acid mainly goes into acrylate esters (resins) — about 60% of total consumption — applied in construction, papermaking, leather, textiles, plastics processing, packaging materials, consumer chemicals, water treatment, oil recovery, and metallurgy.
