Spectrum 10 TimeBase

Spectrum™ TimeBase enables the user to collect time-resolved, sequential sample spectra, either continuously or at user-defined time intervals, for time-resolved measurements or hyphenated experiments using FT-IR and FT-NIR spectrometers. Spectrum TimeBase gives an excellent overview of the complete spectral dataset, allowing the user to see evolution of the absorption features with time at a glance.

TimeBase applications include:

• TG-IR
• GC-IR
• Kinetics

For TG-IR analysis, two powerful pieces of software are used. PerkinElmer’s Pyris™ Software controls the thermal analysis instrument, allowing desired thermal programs to be specified as well as automated triggering of the IR software. Spectrum TimeBase is then used for time-resolved IR data analysis and waits for a trigger from Pyris (supplied via a relay box) by a simple tick box.

TimeBase software provides several different ways of presenting the data, as individual spectra or a stacked plot. The changes with temperature can be examined as the intensities at specific frequencies or as ratios of pairs of peak heights or band areas that can be chosen interactively.

Full manipulation of IR data including Gram-Schmidt plots, individual functional group data, as well as individual spectra recorded during the run is allowed using TimeBase software. In addition, calculated quantitative data can be displayed real-time during time resolved collection. Pyris data can also be imported into TimeBase as the raw data, or as the derivative plot. TimeBase allows for construction of profiles corresponding to intensity of individual spectral bands and even quantitative Beer’s Law or chemometric models.

Additionally, PerkinElmer Spectrum software can be used to allow sophisticated processing and analysis of the individual infrared spectra, such as library searching and comparison against reference spectra.
