Pulp Yield Assesment
Forest Quality offers a low cost measurement of Kraft pulp yield) at kappa 18) based on near infra-red spectra collected from woodmeal using a Bruker MPA FT-NIR. A well tested calibration (Downes et al 2009, 2011) has been used in a wide range of applications including tree breeding, resource evaluation, and studies examining the effect site, age, fertiliser and spacing.
Near Infra Red (NIR) spectroscopy is widely used in agriculture and manufacturing. Application to KPY measurement spans two decades of R&D, demonstrating its ability to provide precise measurements of KPY in samples as small as 1 gm.
Numerous studies have shown NIR offers
Low cost measurement
Expanded application of traditional analyses
Efficient ranking of trees and sites
Precise KPY values that are highly heritable
