Evaporation Loss  |  Volatility Test

Test Method

ASTM D5800


The Selby-Noack features automatic temperature control and vacuum control for running ASTM D5800, Procedure C.  This unit was designed to correlate to the original Wood's Metal method (Procedure A) with no correction factors, and can be calibrated to the lab environment using interchangeable orifice caps.  Constant temperature is maintained with a noble-metal heater instead of hazardous Wood's Metal.

The volatilized material is automatically recovered during the standard Noack test and can be analyzed for phosphorous or sulfur content or other elements.

This compact, self contained unit makes it ideal for small bench space requirements.  

Features & Benefits

  • First commercial non-Wood's Metal heating system
  • 'Tunable' to the atmospheric conditions of each lab
  • Only Noack system to collect volatile products during the test for further evaluation
  • Used for Sulfur Emission Index & Phosphorus Emission Index (PEI)
  • Automated vacuum control & built-in vacuum pump
  • Digital RS232 output for recording of vacuum and temperature
  • Does not require hood placement - eliminates hood effects on vacuum control
  • Self-contained unit with very small-footprint
  • Simple to use and easy to clean
  • CE Mark
