Capabilities

  • Sample accessories are available to facilitate automated measurements of vials, tablets, tubes, and well plates. Perfect for measuring a lot of samples automatically.
  • Representative sampling of heterogeneous materials is made possible by an expandable measurement spot size of up to 5 × 5 mm.
  • Directly measure samples using colored or clear glass bottles, plastic bags, jars, and vials.
  • It contains specialized cells for electrochemical and high- and low-temperature measurements.
  • To go beyond data to answers, extensive software tools automate analyses.
  • Fiber-optic probes are an optional feature for remote sampling of samples too large to fit in the sample compartment.

High Performance

  • The lasers are depolarized to prevent perplexing sample orientation effects.
  • Even after lasers are replaced, a laser power regulator allows for active laser power monitoring and guarantees repeatable laser excitation power throughout the lasers' lifetime.
  • Using Variable Dynamic Point Sampling (VDPS), the measurement area can be changed by the user from 10 μm to 5 mm.
  • To prevent stitching artifacts, a single exposure of the CCD captures the entire spectral range of 3500 to 50 cm-1.
  • Spectra from various excitation lasers and instruments are comparable, thanks to automatic intensity correction.
  • All excitation lasers have the option of automatic fluorescence correction.
  • Artifact-free spectra are guaranteed by a patented algorithm for automated cosmic ray rejection and superior laser line filters.
  • The Triplet spectrograph, which is patented, provides exceptional peak shape and maintains focus at all wavelengths.
  • Patented auto-alignment technology maintains the system in optimal, like-new condition.
  • CCD dark energy profiles are automatically eliminated by patented smart backgrounds.
  • Accurate wavelength calibration across the entire spectrum is provided by multi-dimensional wavelength calibration.
  • Systems that share gratings for several excitation lasers suffer performance losses; this is avoided with optimized gratings for each excitation laser.

Simple to Use

  • An instrument with an adjustable GO button for walk-up operation. All data collection, processing, and reporting steps can be stored so that a user only needs to drop a sample in, press a button, and a report will print out without interacting with the computer.
  • Optimizing the number of exposures and exposure duration eliminates the need for guesswork with autoexposure (patent pending).
  • Easily switching between different types of samples is made possible by autofocusing accessories.
  • The system automatically recognizes smart parts and accessories, and it optimizes alignment and parameters when parts are changed.
  • The software completely automates the calibration and alignment processes. The software takes care of everything; the user just needs to mount the alignment/calibration pod on the device. The process can be guided without the user having to make any decisions.

Databases and Software

  • Algorithms for library searches are tailored for Raman data.
  • The ability to quickly capture repetitive actions into single buttons is made possible by a powerful macro-building tool.
  • With a single action, the user can identify multiple components of a material, thanks to powerful spectrum searching software.
  • All processing operations and collection parameters are automatically recorded by audit trails that are connected to spectra.
  • Omnic Array offers automated array-based sample formats, such as well-plates and tablet arrays, for data collection and analysis.
  • Spectral libraries with a large collection (>16,000 compounds).

Maintenance and Reliability

  • Every laser has an automated system for tracking its usage.
  • All decisions are made by the software, and the calibration process is automated.
  • All that is required of the system is a regular, fully software-controlled automatic alignment.

Laser Safety

Class-1 laser safety is independently certified by the spectrometer. (Note: Class IIIb laser devices, which call for laser safety eyewear and laser safety precautions, include optional fiber-optic accessories and a few other optional accessories.)

Modularity

  • SmartLock technology is used in user-replaceable lasers to achieve repeatable results. Run the standard auto-alignment and automatic calibration procedures after plugging the laser in.
  • Purchase flexibility is provided by modular design. Purchase only what is needed now, with the option to grow later without incurring fees or service requests.
  • It is simple for multiple instruments to share filters, lasers, gratings, and accessories. The device records alignment and calibration parameters for every distinct Smart component and recognizes each component's serial number.
  • These are automatically used whenever the components are installed.

Validation

  • Omnic D/S software provides compliance with CFR 21 Part 11.
  • There is a comprehensive package for DQ/IQ/OQ/PQ validation that includes automated software protocols and copious documentation.

Recommended For

  • Gemology: This includes quickly identifying colored stones and differentiating between natural and synthetic diamonds.
  • Forensics: Identification of illegal drugs. Numerous samples can be measured automatically, and infrared identification is supported for legal backup.
  • Pharmaceutical: Identify salt forms and polymorphs, and describe tablets.
  • Academic research: Helpful in many applied research domains, including material science and biological studies.
  • Nanotechnology: Describe bulk nanotubes and their quality control.
