Terahertz laser reaches 230mW power

Terahertz quantum cascade laser (QCL) shown in scanning electron microscope image by Wang, et al/AIP Advances

THE RECORD for continuous power output from a terahertz quantum cascade laser has been almost doubled to 230 milliWatts, researchers in China have reported. Terahertz wavelengths remain a relatively low-power part of the electromagnetic spectrum, lying between infrared and microwave.…

Blood analysis from within the plastic bag

Professors Blades and Turner used a Renishaw InVia Raman microspectrometer

RAMAN spectroscopy is being used to monitor biochemical changes and inter-donor variability in stored red blood cell (RBC) units, without the need to open the bags and remove samples. Research into the technique has recently been published in the journal…

Agilent catalogue is ‘user-friendly’

Agilent Technologies has introduced its 2013 Essential Chromatography and Spectroscopy Catalogue. The new volume is divided into five sections to help the reader easily navigate the company’s portfolio, which includes general chromatography, sample preparation, GC and GC/MS, LC and LC/MS,…

Shimadzu University helps improve research methods

SHIMADZU University recently held a series of complimentary ‘Sharing best practice’ events at the company’s Centre of Excellence in Milton Keynes. These were open to any Shimadzu customers interested in learning more about how to get the most reliable results…

Microspectrometer is ‘the future’ of Raman spectroscopy

COMBINING high resolution and high sensitivity with short sampling times and a broad spectral range, the new Artemis Raman microspectrometer from Craic can be deployed on many different types of light microscope.   This instrument facilitates the measurement of Raman spectra…

Raman microspectroscope with multiple laser colours

CRAIC Technologies has added further laser wavelengths to its Apollo Raman microspectrometer, with blue, green, red, and infrared now available.  Used in conjunction with a light microscope, the Craic Apollo measures Raman spectra from samples or selected areas of large…

Protocol shows way to improved sulphur determination

A PROPRIETARY inductive coupled plasma – optical emission spectroscopy (ICP-OES) sample preparation protocol allowing regular, reproducible detection of sulphur at trace levels of only tens of parts-per-million (ppm) has been developed by Warwick Analytical Service. The company says the new…

Chemical identification at nanometre scale

ELECTRON microscopy and scanning probe microscopy offer the scientific researcher powerful high-resolution imaging at the nanometre scale, but are poor at identifying the chemical composition of the structures they image. Spectroscopy offers powerful chemical identification, but has resolution limited to…

Turn your optical microscope into a Raman spectroscope

MOST major brands of optical microscope can now have Raman spectroscopy capability added to them through the Apollo Raman microspectrometer from Craic Technologies. This additional instrument allows the collection of Raman spectra from microscopic or larger samples, allowing the specimen…
