“…However, these two methods require the atomization of the sample, since the atoms have to be in their ground state in order to allow the atomic absorption to occur [291]. A variant of AES, laser induced breakdown spectroscopy (LIBS), provides an in-situ quantitative and qualitative analysis of samples and has been used for detecting metals in food [292]- [294], in semiconductor manufacturing [295], in oil [296], [297], and so on [236], [296], [298]- [309]. However it employs a pulsed high energy laser focused on a part of the sample, inducing a high temperature plasma and thus exciting the atoms of the sample, resulting in a small part of the sample being ablated.…”

We establish a set of metal particle detection methods that are suitable for automated inspection of freeze-dried vaccines. We first identify the requirements for freeze-dried vaccine inspection. We then assess metal particle detection methods obtained through a comprehensive literature review with the requirements for automated inspection. In particular, we find inductive sensors, superconducting quantum interference device (SQUID)-based sensors, giant magnetoresistive (GMR)/tunneling magnetoresistive (TMR)-based sensors, THz imaging, hyperspectral imaging, thermal imaging, X-ray inspection, and radio frequency identification (RFID)-based sensors promising for automated inspection of freeze-dried vaccines. However, experiments assessing the applicability of these methods for freeze-dried vaccine inspection are severly limited and future research is required to choose the best performing methods.

“…The conclusion was that LIBS imaging has huge potential as a unique characterization technique capable of simultaneously monitoring the distribution of the metallic precursor, organic additive and support impurities. The other paper to use LIBS was by Burnette et al 132 These authors studied the iridium-based catalysts used in monopropellant thrusters which have been used for decades to manoeuvre spacecraft. Unfortunately, the degradation or loss of the catalyst is known to limit their lifetime.…”
