How can Raman microscopy help the battle to quit smoking? Read this latest application note to find out how the RMS1000 can aid pharmaceutical laboratories quality control nicotine patches via 3D Raman mapping.

Liquid scintillator detectors are widely utilised in neutrino and astroparticle detection experiments. One liquid scintillator that is increasingly being used in large scale detection experiments is linear alkylbenzene (LAB). LAB is an attractive scintillator due to its low cost, high flash point and low toxicity; making it easier to handle than previously used toxic and flammable organic solvents. LAB is commonly used together with the fluor 2,5-diphenyloxazole (PPO) which increases luminescence yield and shifts the luminescence to longer wavelengths.In this application note the properties of the liquid scintillator system LAB/PPO are investigated using time-resolved X-ray excited luminescence spectroscopy with the FLS1000 and XS1 X-ray Sample Chamber.

Forensic investigations often study extremely small samples which may need analysed by multiple techniques. Confocal Raman and Photoluminescence (PL) Microscopy are well-suited techniques for dealing with such samples. This application note details how Raman and PL microscopy can be used as an analysis tool in any forensic laboratory.

In this application note, the hole transfer into a VACNT based hole extraction layer is imaged using steady-state and time-resolved confocal PL microscopy with an Edinburgh Instruments RMS1000 Confocal Raman & PL Microscope.

This customer written application note details how researchers from the Air Force Research Laboratory have outfitted an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer to assess candidate dissolved oxygen sensors.

The gemstone industry suffers massively from forgeries that even highly experienced jewellers cannot determine. Read this application note to discover how Raman microscopy offers itself as a useful technique in the identification of gemstones.

Graphene is the thinnest material known to exist, whilst also being extremely strong - around 200 times stronger than steel. Graphene is an excellent conductor of electricity and heat as it is optically transparent. The applications of graphene are extensive, and include energy storage, photodetectors, and computer chips. In this application note we highlight how Raman microscopy is an essential tool for any material scientist researching graphene.

Semicrystalline polymers are the largest group of commercially produced plastics. Heating and cooling of these polymers between phase transitions is used industrially to shape polymers into their final product. In this application note the RMS1000, with a heated stage, is used to observe phase transitions in two polymers; polyethylene, and nylon-6.

Cooking oils are one of the main components of the human diet. Adulteration of extra virgin olive oil with cheaper oils is a common problem in food fraud. This application note highlights how Raman spectroscopy in combination with chemometrics can be used to identify cooking oil adulteration.

Microplastic pollution is a growing environmental issue. Identification is crucial for assessing their risk to the environment, wildlife, and mankind. Raman microscopy is a great tool for the identification of small microplastics. This application note explores how the RM5 Raman Microscope combined with the KnowItAll Raman database can be used to identify polymers commonly found in the Earths aquatic systems.
