Agilent's new DialPath technology is the first major breakthrough in FTIR transmission measurements of liquids in decades. The DialPath technology makes longer pathlength transmission measurements as easy and quick as ATR makes short pathlength liquid analysis. This sampling accessory has three individual pathlengths that can be accessed in seconds, and is a significant new sampling methodology that simplifies both quantitative and qualitative analysis.
The document introduces Agilent Technologies' new DialPath technology, a sampling accessory featured on the Cary 630 FTIR spectrometer. It is designed to simplify quantitative and qualitative analysis of liquids by allowing longer pathlength transmission measurements as easily as Attenuated Total Reflectance (ATR) makes short pathlength liquid analysis.
The spectrometer acquires approximately 148 scans in 60 seconds at 4 cm⁻¹ resolution, which is sufficient to get an excellent transmission spectrum from virtually any liquid.
The total fill volume of the DialPath cell is approximately 250 microliters.
The FTIR spectra were collected using the DialPath's 100 pm pathlength.
