Product Details

NanoQuest is based on Fourier transform infrared (FT-IR) technology, which is often favored in laboratory spectrometers because it collects spectral data over a wide range. The sensor’s patented micro-electro-mechanical systems (MEMS) technology allows for a continuous-wave Michelson interferometer to be created monolithically on a MEMS chip. This enables detection of all wavelengths simultaneously, and mitigates the effects of motion on sensor stability.

Each NanoQuest comes with an optical fiber and operating software, and can be coupled to most Ocean Insight light sources and accessories to configure systems for absorbance/transmission or reflectance measurements.

Typical NanoQuest NIR applications include authentication of counterfeit products including textiles; characterization and quantification of food, soil nutrients and industrial materials; and compositional analysis of bodily fluids and other biological specimens.

For industrial applications, NanoQuest offers the advantages of scalability, low power needs, and tolerance to vibration and other motion effects. When compared with bulky and more expensive NIR instrumentation, NanoQuest is an attractive option for exploring new development opportunities.

Recommended Configuration - Absorbance/Transmission Measurements
Here's one suggested setup for cuvette-based absorbance measurements with NanoQuest:

  • NANOQ-2.5 - compact FTIR spectral sensor (1350-2500 nm)
  • SQ1-ALL cuvette holder - robust, reliable holder with 1 cm pathlength
  • NANOQ-FIBER-400-VIS-NIR - 400 µm optical fiber
  • HL-2000-HP-FHSA - high-power tungsten halogen source with built-in filter holder and shutter

Recommended Configuration - Reflection Measurements
Here's one suggested setup for probe-based reflection measurements with NanoQuest:

  • NANOQ-2.5 - compact FTIR spectral sensor
  • NANOQ-RPROBE-600-VIS-NIR - 600 µm fiber optic probe
  • HL-2000-HP-FHSA - high-power tungsten halogen source with built-in filter holder and shutter
  • Reflection probe holder - options include the RPH-1 and STAGE
  • Reflection standard - WS-1-SL Spectralon diffuse reflectance standard

Product Overview

  • Covers wider spectral range (1350-2500 nm), at lower cost, than other shortwave IR instrumentation

  • Ultra-compact size (smaller than a deck of playing cards) frees up bench space and makes scalability simpler

  • User-selectable optical resolution (8 nm or 16 nm FWHM) and scan rate provide experiment flexibility

  • Versatile setup options enable absorbance/transmission or reflectance measurements

  • Wider range and lower cost make access to shortwave IR measurements more manageable for a greater number of researchers

  • Rugged enough for industrial applications

  • Can be paired with Ocean Intelligence for qualification and quantification
  • NANOQ-FIBER-400-VIS-NIR is included when you order the NanoQuest

Explore Key Features of NanoQuest, a MEMS-based FT-IR Spectrometer

In this video, we review important advantages provided by the NanoQuest, a compact, MEMS-based spectral sensor with response from 1350-2500 nm (7400-4000 cm-1).

FT-NIR spectroscopy offers a simple tool to identify different types of textiles, with distinct spectral features observed at wavelengths >1350 nm. This approach may be useful for authentication of natural and synthetic consumer textile products.
