Introduction to Field Portable

Field portable X-ray fluorescence spectroscopy (XRFS) has become increasingly prevalent for in situ detection of trace metals, as it is both rapid and cost effective.

In this study, we evaluate the use of field portable X-ray fluorescence (pXRF) as a screening tool for dust source characterisation at two sites in Greenland, a natural site near Kangerlussuaq influenced by dust generated by the Greenland Ice Sheet and an anorthosite mine site located 80 km from Kangerlussuaq.

We have developed inkjet-printed surface-enhanced Raman spectroscopy (SERS) sensors that are specifically designed to work with field portable Raman analyzers for the detection of chemical and biological agents (Tay et al.

Then the spectral model was extended to a real-time foliar map scanning spectra of a field portable Raman spectrometer through calibration model transfer, and the spectral variation between the confocal micro-Raman spectrometer in the laboratory and the portable Raman spectrometer were effectively corrected by the direct standardization (DS) algorithm.

It consists of a SVC HR-1024i high resolution field portable spectroradiometer, with 3-10nm spectral resolution in the range 350-2500 nm, connected with an optical tube to two integrating spheres, one facing upward and the other facing downward, which collect the irradiance received from the sky and reflected from the surface, respectively.

An ASD FieldSpec 4® Standard- Res field portable spectroradiometer working in the range 350-2500 nm was utilized.

The field portable XRF instrument is applied, and the mineralogy and elements input into the models.

Field portable XRF has become a standard field technique, though more often used in a camp setting.

We present a design and the optimization of an irregular-shaped inward-outward (IO) ring-pair magnet array that generates a 1D monotonic field pattern for 2D head imaging in a low-field portable magnetic resonance imaging (MRI) system.

In this paper, we present the design and optimization of a ring-pair permanent magnet array for head imaging in a low-field portable magnetic resonance imaging (MRI) system.

Thus, the development of a non-contact field portable detection method is essential.

Broadly, the requirements align with many of the developmental drivers that have led to the rise of in-field portable detection instrumentation, specifically rapid detection within one hour, ease-of-use, and ≥95% accuracy.

In this paper we describe recent developments in constructing and characterising a low-field portable MRI system for in vivo imaging at 50 mT.

Although the whole cost is not able to compete with LTS MRI, high-field portable MRI are in great demand.

The in-field portable system was benchmarked against a commercial lab-based LC-tandem MS (MS/MS) system for the analysis of PFASs in real soil samples, with the results showing good agreement.

In this keynote address paper, we overview recently published works on the current techniques and methods for automated cell identification with 3D optical imaging using compact and field portable systems.

Field portable gas chromatography-mass spectrometry, GC-MS, have been established as the ‘gold standard’ of chemical identification and quantification for chemical threats however several chemical warfare agents have been shown to evade required detection limits.

Here we present novel method development and instruction in the construction and use of Field Portable Gas Analyzers study of belowground aerobic respiration dynamics of deep soil systems.
