Our Team

Managing Director

Christabel 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 grown the company from a simple portable XRF hire company to one that encompasses all kinds of spectral technology and service offerings.

In addition to her role as managing director, she has had extensive training from the Bruker application scientists to create matrix matched custom calibrations that guarantee clients are achieving the best results from their Bruker portable 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.
