Astoria-Pacific offers wineries a variety of methods for their analytical needs. Depending on the test, two different analyzers are available.

The Astoria®2 Analyzer has been configured to monitor Free Sulfite, Total Sulfite and/or Volatile Acidity. Free and Total Sulfite samples are determined using the DTNB method with Gas Diffusion Membrane. The working range for both Free and Total is 5 – 100 mg/L or 5 – 200 mg/L. Volatile Acidity is an in-line distillation method and is a good choice for laboratories requiring a true VA number, which matches CASH Still. Its analytical range is 0.012 – 0.12 g/100 mL. This instrument has been designed for high throughput, between 48 – 144 determinations per hour; and it is primarily recommended for laboratories with high sample volumes.

The rAPID™-T system is an affordable discrete analyzer for small to large-scale wineries. Astoria-Pacific’s wine customers use the rAPID-T system to analyze enzymatic and other colorimetric assays. The most common tests are: Acetic Acid, Ammonia, Glucose+Fructose, L-Malic Acid, NOPA and Total Sulfite. We have optimized and sell reagent kits for the above tests; however, the system is easily programmable to run various reagent kits from other manufacturers, such as Megazyme, NZYTECH, Randox, ThermoFisher Scientific and Unitech.

We also have experience with the following additional tests:

  • Acetaldehyde
  • L-Arginine/Urea/Ammonia
  • L-Ascorbic Acid (L-Ascorbate)
  • Citric Acid
  • Ethanol
  • Formic Acid
  • Free Sulfite
  • D-Glucose
  • Glycerol
  • D-Lactic
  • L-Lactic Acid (L-Lactate)
  • D-Mannitol / L-Arabitol
  • Potassium
  • D-Sorbitol/Xylitol
  • Succinic Acid
  • Sucrose/D-Fructose/D-Glucose
  • Sucrose/D-Glucose
  • Tartaric Acid
  • Total Starch
  • Urea /Ammonia
