Time-gated Raman plasticizer library

This library consists of time gated Raman spectra of 91 plasticizers included in the Scientific Polymer Products Inc. Plasticizer Kit‡. The sample list can be found in the file: SampleDetails.csv. Plasticizers were measured at least in duplicate. Data was collected on a PicoRaman spectrometer (Timegate Instruments) using a 532 nm pulsed laser. The spectrometer was coupled through a fiber-optic probe (BAC102, B&W Tek). Sampling conditions were selected to minimize measured fluorescence and accompanying noise in the time gated window. Parameters of Laser Power (mW) and collection time (s) were selected to achieve a Signal-to-Noise Ratio (SNR) exceeding 100. Collection times are reported in seconds and the Timegate software metric of Sub Acquisitions (SA) where samples were collected using 100 SA (13 seconds) or 300 SA (39 seconds). Some samples had significant fluorescence interference after time-gating and could not achieve an SNR >100. These samples are included in the library as is.
Specific information regarding the sampling conditions for each plasticizer are included in the file: SampleDetails.csv, and Python code used to process the data can be found in a Jupyter Notebook file in a GitHub repository: https://github.com/usnistgov/TGRS-Plasticizer-Library.
