The Team

Christabel Brand
Managing Director

Christabel and Nigel established Portable Spectral Services back in 2011 with the aim of furthering the use of handheld XRF within the mining industry. From small beginnings, Chris has seen the company grow from a simple hire company to one that encompasses all kinds of spectral technology.

Chris works in many capacities within the company. In addition to her role as managing director, she works as the Bruker application scientist creating matrix matched calibration to guarantee clients are achieving the best results from their XRF’s. As a top-notch scientist and problem solver, Chris can often be seen teaching and supporting staff members with technical applications and trouble shooting.

The large variety of applications that go with the spectral technology is what keeps the job interesting, with each day being different. She says, “one day it is a lithium calibration the next it is seaweed.” She loves working with people from such a variety of industries that utilise this technology.

Chris has worked in laboratories for the last twenty-five years, including managing the assay laboratory in the gold refinery in Kalgoorlie. She has also had extensive training from Bruker in creating all kinds of custom calibrations and everything to do with handheld XRF. 

Chris holds a Bachelor of Science in Medical Science and a Master of Science in Infectious Diseases.
