Application Area:

Conformational analysis

Very handy to use. It is especially good for my applications because it is not necessary to purge the spectrometer chamber by changing samples. Much better than the conventional liquid IR cells.

At the heart of the Pearl accessory is Specac's innovative Oystercell assembly, which forms a fixed pathlength without spacers or fasteners. The top part of the cell can be simply lifted out of the way to allow for fast and easy application and cleaning of the sample. 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 samples such as oils and greases.

Application NoteSpectroscopy

Quantifying simeticone in over-the-counter medicines using FTIR spectroscopy

In this application note, Specac presents experimental data on the use of Fourier transform infrared (FTIR) spectroscopy in the quantification of simeticone in over-the-counter medicines, and introduces the Pearl liquid transmission accessory. Quantification of the Active Pharmaceutical Product (API) in a finished product is vital to ensure the end consumer gets the correct dosage of the drug. Too little and the desired effect may not be achieved, too much and there is a risk of overdose. FTIR spectroscopy affords a rapid cheap method for the routine testing of a wide range of pharmaceuticals when enabled by time and effort saving transmission accessories. An example of recent interest to the industry is the quantification of simeticone in medicinal formulations found on the high street.

FTIR spectroscopy: Sampling accessories to boost your research

Fourier-transform infrared (FTIR) spectroscopy is used to probe the molecular vibrations of a sample, generating a chemical fingerprint from the molecules present within the beam of light. The technique has been employed in numerous ways across multiple fields, but whatever the aim of the experiment, an accessory is required to contain the matter under study and direct the light onto it.

In this application eBook, we review the literature for some of the most advanced FTIR spectroscopy products and explore cutting-edge research across a diverse range of fields, including sections on:

  • Liquid transmission analysis – from the analysis of biodiesel blends to the detection of fake fish oil
  • Attenuated total reflectance – the basics, penetration depth, advanced measurements, and more
  • Advanced spectroscopy – including catalytic studies and the spectroscopy of gases

Traditional Omni-Cells vs the Pearl Accessory

Traditionally, a vertically mounted liquid cell, such as the Omni-cell, was used to record IR spectral measurements. This application note shows how the Pearl™ Liquid Transmission Accessory has been designed to easily and quickly record highly repeatable IR spectral measurements for a wide variety of samples with high spectral resolution.


Application NoteMaterials

IR Spectra of Grease: Pearl vs Quest ATR

This application note demonstrates that The PearlTM liquid transmission accessory is perfect for measuring IR spectra of ‘sticky’ and relatively immobile liquid samples like greases and lubricants as easily, quickly and reliably as a comparable ATR technique, such as with the QuestTM.

Analyzing Milk Using the Pearl IR Accessory from Specac

Spectral analysis of milk to determine fat and lactose content is simple and fast when using the Pearl liquid IR transmission accessory. Whether checking retail milk quality or ensuring the health of newborn calves, FTIR analysis is an invaluable technique for monitoring a herd’s milk production, as well as fertility and even CH4 emissions. The ease, speed and accuracy of this technique contributes to a cost-effective dairy management system and encourages healthy cows and high-quality dairy products for consumers.
