New UV laser source for CRAIC Technologies’ 20/30 PV™ Microspectrophotometer

The introduction of new UV laser sources will dramatically enhance the capabilities of the 20/30 PV™ microspectrophotometer from CRAIC Technologies in terms of both fluorescence and photoluminescence microspectroscopy.

The major application will be to serve as an intense excitation source for fluorescence and photoluminescence (PL) microspectroscopy. This will broaden the range of materials that can be caused to emit photons via a luminescent process.

The 20/30 PV™ microspectrophotometer combines the latest technologies to allow the user to see and measure UV-visible-NIR range transmission, absorbance, reflectance, emission and fluorescence spectra of sample areas smaller than a micron across. Thin film thickness and colour spaces can also be determined.

CRAIC Technologies launch GeoImage™ for petrographic analysis

GeoImage™ is the latest Vitrinite Reflectance Measurement System from CRAIC Technologies and is used to determine the grade of coal and coke by vitrinite reflectance as per the ISO 7404-5 and ASTM D2798 standards. These procedures ensure that coal blends used in energy generation and steel making are optimal and consistent from batch to batch.

Designed for use with petrographic microscopes, GeoImage™ can also be used in conjunction with CRAIC’s microspectrometers to also acquire reflectance and fluorescence spectra of coal samples, and take high resolution colour images too.

GeoImage™ also features an automated point counting module where hundreds of points are measured on the sample. Using statistical data analysis, the amount of vitrinite* in the coal blend, its thermal maturity and thus its energy content can be quickly determined.

For more information about GeoImage™ and other products from CRAIC Technologies, please contact us.

* Vitrinite is a maceral of coal and is comprised of various polymers, cellulose and lignin. Measuring the amount of light reflected by vitrinite macerals is a key test to determine the thermal maturity of the coal blend and its suitability for steel production. The procedure has been standardised by a number of international bodies including both ISO and ASTM.

 

 

 

 

 


CRAIC’s Technologies MP-2™ Photometer can upgrade your microscope

The CRAIC Technologies MP-2™ Microscope Photometer is designed to add photometry and imaging to an optical microscope. With a spectral range from the deep UV to the near infrared, the MP-2™ is better described as a microscope radiometer. It is limited only by the microscope’s optics.

The CRAIC MP-2™ microphotometer enables collection of transmission, reflectance or even fluorescence and luminescence photometric data of microscopic samples.

mp-1The MP-2’s solid state detectors have dynamic ranges and sensitivities greater than PMTs or imaging systems and with complete software control, either broad- or narrow-band, photometric intensity measurements can be made. Typical applications include:

  • Cytophotometry & immunohistochemistry
  • Cytofluorimetry & immunofluorescence
  • Intracellular calcium measurements
  • Gemology & mineralogy
  • Thickness measurements
  • Ion & pH measurements
  • DNA analysis
  • Photoreceptor analysis

UHP-T-MP: Excellent for Optogenetics/fluorescence excitation in microplate applications

batch5-057The UHP-T-MP series of Ultra High Power LEDs, by Prizmatix, feature a powerful rectangular (3:4) homogeneous collimated beam useful in many demanding applications such as direct microplate illumination without a light guide, fluorescence microscopy and machine vision.

Optimal illumination of standard 96 well microplates from a working distance of about 40 cm is realised by its aspheric optics, and the USB-equipped LED controller supports CW or pulsed operation via a TTL trigger. LED intensity can be set via a pot or external analogue voltage input.

The UHP-T-MP is available in blue – 455 nm, green – 528 nm or red – 630 nm wavelengths, and can be used coupled to an optical fibre or liquid light guide, or just as a collimated light source.

Key features

  • Single chip Ultra High Brightness LED
  • Precisely adjustable, stable power
  • 3:4 aspect ratio
  • CW or pulsed operation
  • USB interface
  • Long life (no consumable parts)

Long-range Z-axis nanopositioning stage is especially designed to hold multiwell plates

The Mad City Labs‘ Nano-ZL Series are long range, Z-axis nanopositioners specifically designed to hold multiwell plates used in biomedical research. High-throughput single cell fluorescence microscopy and high speed, high resolution confocal imaging can be accomplished while simultaneously adjusting the Z-axis position to remove the effects of multiwell plate irregularities.

The Nano-ZL Series has true flexure guided motion and contains internal position sensing for a resolution of better than 1 nm over the full 500 µm travel range, and sub-nanometer for the shorter 100 µm travel range. In addition to high resolution spatial imaging, the Nano-ZL step response allows entire Z-section acquisitions with minimal photo bleaching. For more information, please contact us.

“MatoS & RandaS” are fresh, new SERS substrates cooked up by Ato ID

Ato ID has issued performance and application details for their next-generation of disposable glass substrates for Surface Enhanced Raman Spectroscopy (SERS) and/or Surface Enhanced Fluorescence (SEF).

The new smaller AtoID ‘MatoS’ gold and ‘RandaS’ silver Plasmonic Sensor Substrates are available in addition to the existing 1″ square ‘Randa’ and ‘Mato’ ranges and continue to deliver up to 8x more sensitivity than leading rivals.

These new ½” long small form factor slides are individually vacuum packed in 1.5 ml microcentrifuge tubes enabling easier handling for fresh, on-the-spot analysis of immersed material.

  • Size: 12.5 x 5 x 1 mm
  • Active area: 3 x 5 mm
  • Excitation wavelengths:
    • Silver RandaS: 442 nm to NIR
    • Gold MatoS: 600 nm to NIR

For extra information about these new SERS substrates from AtoID, please contact us.


New SERS/SEF substrates significantly enhance Raman signal

sers-substrate-glas_43The Ato ID™ Randa Plasmonic Sensor is designed to offer good results in both the visible and IR wavelength ranges for both Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescence (SEF).

Features

  • Ideal for visible and IR laser wavelengths
  • Significantly enhances Raman signal
  • Coated with 99.99% silver
  • Active area: 4 x 4 mm (typical)
  • Overall carrier size 25 x 25 x 1 mm thick
  • Compatible with use of cover slip over the active SERS area
  • Developed specifically for high sensitivity trace detection applications

The base substrate is soda-lime glass which exhibits relatively weak inherent Raman scattering and so does not interfere with the sample signal. The active region comprises a pure silver coating over the proprietary nanofabricated base (patent pending). The monolithic structure eliminates risk of contaminants that can arise with glued or chemically treated types. All ‘Randa’ Raman substrates are vacuum sealed in a cleanroom environment for ease of handling. Please contact us for more information.
