Moisture and Ash in Biomass

Better analysis leads to better quality

If you produce or consume biomass fuels, you know that quality is critical to your success, and you know that moisture and ash content control are critical to biomass fuel quality. Too much moisture and you get poor efficience and high emissions. Too much ash and you get fouling and slagging. And if either of those is uncontrolled, purchase contracts can fall through. Computrac can help.

Computrac provides quick and accurate primary measurements of both moisture and ash content for a wide range of biofuels. Because Computrac is a primary measurement, it correlates very strongly to conventional methods, but can deliver results with better repeatability in less time, regardless of operator skill. And because Computrac does not use an optical method, you don’t need to generate a new calibration curve if your feedstock is a different color this week than it was last week.

So if you currently use an oven, a muffle furnace or an optical system to test your biomass pellets or feedstocks, give us a call. Our experienced team of analytical chemists and applications consultants will help you find the solution that’s right for your product, your application, and your business.


  • Quick and Simple ash testing:

    Get ash and moisture content readings from a single sample in 30 minutes. No muffle furnace, dessicating chamber, or analytical balance required.

  • Ideal for multiple feedstocks:

    Hard woods, soft woods, corn stover, particulate fuels: as a primary measurement of moisture, solids and ash content in biomass, Computrac can handle any feedstock.

  • Durable:

    Every Computrac® MAX® is made in the USA with an all-steel enclosure. Computrac was built to deliver accurate results whether it’s in the lab or next to the boiler.

  • Reliable:

    Computrac has been known for rugged reliability since the first instrument was built in 1981. All Computracs are designed and built in Arizona

  • Accurate:

    Correlate preciesly with ASTM methods for biomass, including E1755, E1756, and E1534.
