Plastics Identification Using ATR-FTIR Spectroscopy
The massive production of plastics has led to a throw-away culture rendering plastic pollution one of the biggest environmental issues. One solution to prevent plastic pollution is improving waste management systems and recycling. To facilitate plastics separation, the Plastics Identification Code (PIC) was introduced. When a PIC identifier is absent, spectroscopic techniques, such as Fourier Transform Infrared Spectroscopy (FTIR), can quickly identify and sort plastics for recycling.
ATR-FTIR of Blood Serum Using a Heated ATR Accessory
This application note demonstrates the use of ATR-FTIR spectroscopy for the analysis of human serum albumin. An IR5 FTIR spectrometer was used, equipped with a heated ATR accessory, to help tackle the issue of strong water absorption bands masking...

In this application note, the transition-metal dichalcogenide tungsten diselenide (WSe2) is characterised using the RMS1000 Confocal Microscope with five imaging modalities: reflected brightfield and darkfield, Raman, photoluminescence and second...
Photoluminescence of Lanthanide-based Optical Probes
Optical probes based on lanthanide complexes are of particular interest in the biomedical field and life sciences due to their unique magnetic and photoluminescent properties. In this application note, an Edinburgh Instruments FS5 Spectrofluorometer...
Rapid Excitation Emission Matrix Analysis of Single Wall Carbon Nanotubes
Single-wall carbon nanotubes (SWCNTs) have unique electrical, thermal, mechanical, and optical properties which make them attractive for a wide variety of applications; ranging from drug delivery to battery electrodes. In this application note the...
UV-Vis Spectroscopy for Characterising the Optical Properties of Gold Nanoparticles
UV-Vis spectroscopy is routinely used in analytical science in part because it is a simple way of studying a sample’s optical properties over the UV and visible regions of the electromagnetic spectrum. Here, we used the DS5 UV-Vis Spectrophotometer...
Characterisation of SERRS Nanoparticles Using UV-Vis and Raman Spectroscopy
Surface-enhanced resonance Raman scattering (SERRS) is a technique that offers unparalleled sensitivity and specificity in spectroscopic detection and is promising for many applications in analytical research. In this new Application Note, we use...
Pesticide Detection on Apple Skin Using SERS
Protecting food crops is vital to the world’s food chain, and pesticides are a critical tool to kill, repel, and control pests. One method to reduce the dangers of pesticides is limiting the allowed concentration used on crops. This is controlled by...
Whole Blood Analysis Using UV-Vis Spectroscopy
Point of care diagnostics have benefited from the marriage of spectroscopy and biofluidics, helping to address healthcare challenges from cancer screening to viral detection. The Ocean ST microspectrometer is an appealing option for POC applications...
