Accessories and Attachments

The most suitable VIR system can be configured by selecting accessories matched with applications required. The newly developed MultiChambIR attachment allows users to switch three measurement modes from transmittance, ATR and DR in one attachment. Best suited to incoming inspection of variable samples such as powder, solid and liquid.

Combination with MultiChambIR Attachment

Up to three measurement modes in one attachment


External connection optics allows users to install up to three attachments in one system and to simply by switch from one to another. Furthermore, Universal optical base enables users to freely customize optics by placing mirrors and sample holders onto the base. Therefore, even a large sample or an attachment which cannot fit in the main compartment, can be applied.

Combination with External Connection Optics

Combination with External connection optics

A wide variety of measurement attachments are available.

Name of Attachment Main Application / Feature
SmartTech Attachment Qualitative measurement of powder and solid sample
Fiber Interface Attachment Process monitoring
Long Path Gas Cell Attachment Quantification of gas concentration
Single Reflectance ATR Attachment Surface analysis of powder, solid and liquid sample
NIR Specular Reflectance Attachment Non-destructive measurement of food and medicine
IRT-1000 Micro IR Attachment Foreign object
Autosampler Attachment High throughput analysis of drugs, etc.
Transmission Measurement Attachment Qualitative / quantitative analysis of film sample
MultiChambIR Attachment Three measurement modes (Transmittance/reflectance, diffusive reflectance and ATR) in one attachment

System Configuration Examples

Dedicated accessory configurations include gas cells, microscopes, NIR fiber optics, and open path analyzers. The MPS sample compartment allows connection to commercially available FTIR accessories. The system is designed for high performance in the laboratory and in the field.

External Connection Optics

Qualitative, surface and quantitative analysis can be carried out in one system.


Foreign Objective Analysis

A wide range of sample sizes from centimeter to micron can be applied.


Universal Optical Base (Gas Analysis)

A wide range of gas concentration can be applied by attaching gas cells with several different path lengths.




Field-Rugged FTIR Microscopy System (VIR-9000 series with the IRT-1000VIR)

VIR-9000 Field-rugged FTIR Series

A portable FT/IR microscopy system has been designed by coupling the VIR-9000 series portable FTIR spectrometer with the IRT-1000VIR in-compartment microscope. This analysis system is compact and lightweight for field operations. Rather than taking the samples from the field to the lab for analysis, this system provides micro-FTIR analysis on-site, wherever the sample may be located. Optional ATR objectives allow rapid and simple measurements without extensive sample preparation. Three types of ATR objectives, ZnSe, Ge, and Diamond ATR elements make it possible to measure a wide variety of samples, such as hard solid samples and/or high refractive index substances including carbon filled compounds.

Contaminant Analysis in the Field

Portable FT/IR

The figure shows contaminant analysis in the field using the VIR-9000 Series portable FTIR spectrometer with the IRT-1000VIR compact IR microscope using a diamond ATR objective. The contaminant is Polyethylene.
