The Bentley FTS/FCM series represents the latest in state-of- the-art technology for automated milk analysis at up to 600 samples per hour. Engineered in accordance with Bentley Instruments’ rigorous design principles, the FTS/FCM provides precise and accurate measurements. The FTS/FCM comprises two separate modules—the Bentley Flow Cytometer (FCM), and the Bentley Fourier Transform Spectrometer (FTS). The FCM measures the somatic cell count of the milk samples while the FTS simultaneously measures the milk composition, including fat, protein and lactose. After first being stirred, the milk is drawn from a sample vial and delivered to both measurement modules. The sampling, sequencing and identification of the sample vials are functions performed by the Autosampler.
Fully integrated software controls
With this series, control of both the FCM and FTS modules is integrated into a single Windows-based software program. The simple and intuitive graphical user interface is designed for easy operator use. The software’s sophisticated data export/reporting functions and network access capability allow laboratory supervisors to monitor instrument status and analyze results remotely.
The FTS component analyzer uses an industrial Fourier Transform Spectrometer (or FTIR) that captures the complete infrared absorption spectrum of the milk sample for component analysis. Collecting the complete spectrum allows the calibration to be based on all spectral characteristics of each particular component. The infrared spectrum is permanently stored so that at any time in the future other calibrations may be retroactively applied to your data.
The FCM is the next innovation in the evolution of our world-renowned instruments for somatic cell counting. Based on a highly stable solid-state laser induced fluorescence, this module is capable of delivering an accurate and timely warning for mastitis onset.
This FTS/FCM series exceeds the IDF 148A standard and ICAR requirements for somatic cell counting and IDF 141C:2000 and ICAR requirements for component measurement employing AOAC approved methodology.
Technical overview of FTS module
This module uses a Fourier Transform Spectrometer (or FTIR) to capture the complete infrared absorption spectrum of the milk sample for component analysis. Collecting the complete spectrum allows the calibration to be based on multiple spectral characteristics of each particular component. The optical deck of the FTS is housed in a hermetically sealed enclosure, ensuring enhanced temperature stability and environmental robustness. The air in the sealed deck is pumped out, leaving the deck under vacuum. The combination of the hermetic seal and removing the humid air greatly reduces the humidity load on the enclosed desiccant, virtually eliminating the preventative maintenance task of frequent desiccant regeneration.
Technical overview of FCM module
The FCM is based on proven flow cytometry methodology for somatic cell counting. This system uses a proprietary process based on the principle of laser-based flow cytometry to determine the somatic cell count in raw milk. Flow cytometry is an extremely powerful and versatile technique and is the method of choice in the medical field for detecting, analyzing and sorting cells. The Somacount FCM is the result of 15 years of experience and research in flow cytometry; the first instrument was developed in 1991.
Remote diagnostic capabilities
The web-enabled diagnostic features of the FTS/FCM series allow Bentley Instruments to access your machine from any location. This enables your laboratory personnel and Bentley Instruments to collaborate and analyze all system functionalities, no matter where the instrument is located.
