IS-Instruments: Sampling Services

The in-house sample service is a practical choice if spectroscopic measurements are needed occasionally or on a one-off basis. When users send a sample, IS-Instruments will take the measurements without needing a spectrometer or specialized expertise.

With various equipment, IS-Instruments can discuss user needs, identify the instrument that will most likely deliver the best results for the sample, carry out the measurements, and send the results.

Benefits of Using the In-House Service

  • Affordable answer to sporadic and one-off sampling requirements
  • Fast turnaround for results
  • No significant expense for the purchase and upkeep of an instrument
  • There is no necessity for qualified individuals to operate instruments or analyze results
  • Availability of a range of equipment and wavelengths

Instruments for Measurements

  • ODIN: Deep UV Raman spectrometer that is perfect for monitoring fluorescing substances and delicate biologics
  • Raman spectrometer: Presents extremely comprehensive chemical information without damaging the sample
  • HES Spectrometer: Can be used for a variety of spectroscopic methods
  • Aura: Gas Raman spectrometer for monitoring numerous gas species at the same time

ODIN Deep UV Raman Spectrometer

ISI has created ODIN, a small, deep UV Raman spectrometer using a Toptica laser that operates at 228.5 nm.

Deep UV Raman spectroscopy can detect, identify, and quantify compounds at considerably lower concentrations than near-UV, visible, or infrared equipment. Deep UV is especially effective for detecting complex biomolecules, chromophores, and aromatics with strong fluorescence sensitive to deterioration when detected at higher-powered wavelengths.

Raman Spectrometer

The core spectrometers acquire information from the target substance via a fiber rather than an aperture, making them substantially more sensitive to detecting Raman scatter.

ISI provides a range of excitation wavelengths, including 355 nm, 535 nm, 785 nm, and 1064 nm, and will pick the wavelength most suited to the sample.

HES Spectrometer

Due to employing a fiber rather than a slit to concentrate light on the target material, all spectrometers in the HES range are high throughput devices.

As a result, the signal-to-noise ratio is better than a Czerny Turner instrument. Depending on the material being tested, the sampling service will choose a 1 mm, 2 mm, or 3 mm fiber with a photon-counting CCD.
