Job Description

A technical research assistant position is currently available at the Department of Chemical Engineering, Stellenbosch University, South Africa, for routine, wet chemistry analysis of plant biomass samples. The conversion of lignocellulosic plant biomass into valuable products requires compositional analysis of the material during various stages of processing. A wet-chemistry method forms the basis of the compositional analysis, utilising solvent-based removal of extractives and subsequent acid-hydrolysis of carbohydrates. A research technician is required that will complete these routine wet-chemistry based analyses in a highly-accurate, quantitative manner with a high level of attention to detail, to ensure that the resulting analytical results are reliable. Thorough training of the required methods will be provided, to the selected candidate.

The position is available for one year with the option to renew. Stellenbosch University supports a stimulating research environment where new knowledge and skills can be developed, shared and applied to the benefit of the South African community.

Key tasks and duties will include:

Preparation of biomass samples for analysis through scientific subsampling and comminution methods

Solvent-extraction with Soxhlet methods

Acid-hydrolysis with gravimetric measurement of yields

Ash content determination through combustion

Calculation of compositions based on mass yields and compositions of liquid products

Excel-based reporting of results

Basic maintenance on equipment used for the analyses

Ordering of glassware and chemicals for the analyses

Contribution to a clean, safe and well-managed laboratory space

A diploma, advanced diploma, BTech or BSc in Analytical Chemistry, Wood Science or a related field, with at least 5 years of laboratory-based experience in the application of quantitative methods in wet chemistry. Reference letters are to be provided to confirm previous experience with the quantitative wet chemistry methods described above, and only candidates that can provide these, will be considered for the position.

Compile a cover letter, a full curriculum vitae, academic transcript and letters of reference into one document and submit to Prof J Gxc3xb6rgens, Department of Chemical Engineering

Closing date for applications: 15 October 2023
