Analyze volatile liquids using transmission spectroscopy

For more volatile samples, there is an injection access port in the top Oyster, so the cell assembly does not have to be fully opened. At all times, the sample can be viewed through the two windows, allowing the user to ensure that no bubbles have been trapped.

The Oyster Cell can be cleaned very easily and quickly using tissue and an appropriate solvent.
 

Features

• Easiest liquid FTIR sampling system available
• Faster and more reliable than traditional liquid cells, saving time and money
• Very accurate and repeatable pathlengths, including the option of wedging to eliminate troublesome fringing
• Various pathlengths and window materials, which can be changed in seconds
• Handles viscous materials with ease

Accurate transmission pathlength

The Pearl™ has been designed to provide a more accurate pathlength than can be achieved when using a traditional liquid transmission accessory, with pathlengths repeatable to significantly less than 1μm thanks to the innovative Oyster Cell.

The Oyster Cells have the unique feature of being offered as either parallel or wedged cells to eliminate troublesome fringing patterns.
 

Interchangeable FTIR transmission windows

Pearl™ can be fitted with ZnSe or CaF2 windows which can be interchanged in seconds. These Oyster Cells are available in six pathlengths, 25μm 50μm, 100μm, 200μm, 500μm and 1,000μm.

Key Features

• The easiest to use FTIR liquid sampling system available
• Faster, more accurate and more repeatable than traditional liquid cells
• Wedged option to eliminate troublesome fringing completely
• Different pathlengths and window materials in seconds
• Handles viscous materials with ease

Applications


 

For more volatile samples, there is an injection access port in the top of the Oyster™ cell so that the assembly does not have to be fully opened. The sample can be viewed through the two windows, allowing the user to ensure that no bubbles have been trapped.

The Oyster™ cell can be cleaned very easily and quickly using tissue and an appropriate solvent. The Pearl™ has been designed to provide a more accurate pathlength than can be achieved using a traditional liquid transmission accessory, with pathlengths repeatable to significantly better than 1 µm thanks to the Oyster™ sample holder.

Oyster™ cells have the unique feature of being offered with either parallel mounted windows, or windows with a slight wedge angle to remove troublesome fringing patterns.
Pearl™ can be fitted with ZnSe or CaF2 Oyster™ cell assemblies which can be interchanged in seconds. Oyster™ cells are available in six pathlengths from 25 to 1000 µm.

The Oyster™ cell mechanism is so easy to use that it makes the Pearl™ accessory suitable for handling highly viscous sample such as oils and greases.

Baseline Benchmark
 

Specac believe that it should be possible to quickly and easily switch between sampling accessories. To facilitate this, we have developed the Benchmark™ Baseplate system which ensures that a single instrument-specific baseplate can be used for all Benchmark™compatible accessories. You only ever need as many baseplates as the number of different spectrometer models in your laboratory.
