Assessment of multiple herbicide protection seed treatments for seed-based restoration of native perennial bunchgrasses and sagebrush across multiple sites and years.

The invasion of exotic, annual plant species is a leading contributor to ecological degradation in drylands globally, and the use of pre-emergent herbicide to control these species is common. Pre-emergent herbicides pose challenges for seed-based restoration due to toxicity to the seeds of desired species. Herbicide protection (HP) technologies pose a potential solution by using activated carbon seed treatments to protect desirable seeds from herbicide exposure.

Quantifying low levels (<0.5% w/w) of warfarin sodium salts in oral solid dose forms using Transmission Raman spectroscopy.

In this feasibility study Transmission Raman spectroscopy (TRS) has been used to build quantitative models for warfarin sodium and warfarin sodium clathrate. The type of warfarin present in manufactured tablets may affect product quality. Models were used to predict warfarin sodium in commercially available tablets at extremely low dosage levels (0.

Through-container, extremely low concentration detection of multiple chemical markers of counterfeit alcohol using a handheld SORS device.

Major food adulteration incidents occur with alarming frequency and are episodic, with the latest incident, involving the adulteration of meat from 21 producers in Brazil supplied to 60 other countries, reinforcing this view. Food fraud and counterfeiting involves all types of foods, feed, beverages, and packaging, with the potential for serious health, as well as significant economic and social impacts. In the spirit drinks sector, counterfeiters often 'recycle' used genuine packaging, or employ good quality simulants.

Rapid quantification of low level polymorph content in a solid dose form using transmission Raman spectroscopy.

This proof of concept study demonstrates the application of transmission Raman spectroscopy (TRS) to the non-invasive and non-destructive quantification of low levels (0.62-1.32% w/w) of an active pharmaceutical ingredient's polymorphic forms in a pharmaceutical formulation.

Comprehensive quantification of tablets with multiple active pharmaceutical ingredients using transmission Raman spectroscopy--a proof of concept study.

Transmission Raman spectroscopy is a potent new tool for content uniformity testing in pharmaceutical manufacturing enabling rapid bulk sampling of a material by non-destructive means. In this proof-of-concept study, we present, for the first time, comprehensive quantification of all the constituents in a set of tablets consisting of 5 components (3 APIs and 2 excipients) by this method. The nominal concentration of individual components ranged from 1 to 85% (w/w).
