The transparent witness: forensic examination of glass evidence at the Bundeskriminalamt

Glass_28-6_F1sThis article is is a fascinating look into the use of laser ablation inductively coupled plasma mass spectrometry in forensic examination of glass fragments. These are often associated with crime scenes and easily “attach” to any people near them. Thus, they can be used to link criminals to their crime and to provide information on where a glass fragment might have originated.

Glowing colours of foods: application of fluorescence and chemometrics in food studies

FL_28-6_F1-sWhilst the major components of food are usually non-fluorescent, many minor food components that affect its nutritive, compositional and technological quality are fluorescent. Given its sensitivity, ease of use and non-destructive nature, this makes it useful in many applications around monitoring food processing and in fundamental food research.

The CAL(AI)2DOSCOPE: a microspectrophotometer for accurate recording of correlated absorbance and fluorescence emission spectra

Micro_28-6_F2-sThe CAL(AI)2DOSCOPE (Cryogenic Absorption/Luminescence Alignment Independent Alternative Intermittent Detection Optical µSCOPE) is a microspectrometer that was constructed with the aim to facilitate the correlated investigation of absorption and fluorescence emission properties of nanovolumic protein samples under modulatable actinic illumination.

Synchrotron infrared near-field spectroscopy in photothermal mode

Near-Field_28-6_F3-sThis article demonstrates the capability of the near-field method to probe polymer microspheres within a protein matrix, and we present the first IRSR photothermal near-field Fourier transform infrared (FT-IR) spectrum from within an individual biological cell, which establishes the feasibility of hyperspectral mapping at sub-micrometre resolution in a practical timescale.

Change is in the air

Next year, a new version of ISO/IEC 17025 will be published, which is going to mean changes for all those involved in quality systems. Peter Jenks investigates.

Into the laboratory… TOS still reigns supreme

Sampling_28-6_F7-sKim Esbensen and Claas Wagner continue to stress that grab sampling is still an absolute no-no regardless of the size of the sampling device or the sample.

Are they among us? Screening for drugs of abuse and new psychoactive substances in pooled human urine and wastewater samples

MS1_28-5-sThe study of metabolites in our sewage systems is not new, but there are particular difficulties with identifying the metabolites from new psychoactive substances, or “legal highs”. The authors describe a wide range of sample collection methodologies and their analysis with mass spectrometry.

Analysis and sequencing of nucleic acids by matrix-assisted laser desorption/ionisation mass spectrometry

MS2_28-5-sThis article gives a most useful overview of the analysis and sequencing of nucleic acids by matrix-assisted laser desorption/ionisation mass spectrometry, which should interest all readers and may well serve as a useful tutorial article.
