Handheld Raman



SciAps Handheld

Raman Spectrometers

are the robust, battery-powered dispersive Raman spectrometer designed for the non-destructive, real time identification of solids, liquids, pastes and slurries. They have a wide range of applications for material identification, including plastics, organometallic compounds, pharmaceuticals, botanical specimens, octane number in fuels, edible oil, rocks and minerals.

SciAps' lightweight portable Raman spectrometers can collect samples through sealed bags, transparent bottles, flasks, vials, and ampoules, protecting users from direct exposure to hazardous substances. They are lightweight, have no moving parts, and can operate continuously for five hours on their rechargeable battery, allowing them to be used in challenging field applications in addition to laboratory research.

The analysis methods or acquired data can also be communicated with a computer via USB connection for the ultimate portability.

Basic functions with 785 nm laser


Spectra Taken through 8mm Glass Vials

The Inspector supports advanced chemometric algorithm processing which is required for materials that are difficult to discriminate. Methods can be created with multivariate algorithms for pass/fail discrimination or simple correlation models can be created for searching material libraries.


785 nm for geology


Cinnabar (HgS) was a common red pigment used in historical times and the principal ore mineral of mercury.

The samples above were obtained from various locations and identified with the RockHound. Cinnabar has primary peaks at 254, 277, and 340 cm-1 in the Raman fingerprint region. A weak band at 1008 cm-1 has been identified as gypsum.

Lower Frequency Region used for Pigment Identification

Lower frequency region used for pigment identification.

The pigment has been identified as red ochre, or hematite, with peaks at 280, 406, and 608 cm-1. The 280 cm-1 peak was slightly offset to frequencies lower than the standard 293 cm-1 band in hematite because this peak overlapped with the lattice modes of other minerals in the sampling area (e.g., calcite).


1030 nm laser eliminates or mitigates fluorescence


Elimination of competitive flouresence

While 785-nm laser cannot identify the above explosive precursor (3,4-DNT) and pharmaceutical excipient (Folic Acid), the Inspector with the 1030-nm laser can obtain very distinguishable peak characteristics.

The influence of competitive fluorescence may overwhelm the Raman spectrum in lower excitation systems including 785 nm laser excitation. A longer wavelength laser excitation in Raman spectroscopy can be used to eliminate or mitigate such influence, but the longer wavelength laser excitation results in a sacrificed Raman intensity with a ratio of 1/λ4.

This issue is overcome with a low temperature cooled class III-IV semiconductor detector that has high quantum efficiency in the region of interest.


Microscope & micrometer-level positiong


Raman microscopes have become valuable analytical tools in pharmaceutical, plastics, semiconductor, and geology applications due to their high sensitivity and ability to analyse heterogeneous samples. A digital microscope and a positioning stage are available to perform micrometer-level positioning and inspection, allowing images to be captured for image analysis and published materials.
