Optimal for qualitative IR transmission analysis of organic liquids, materials soluble in organic solvents, semisolids and pastes, the card's microporous substrate permits rapid solvent evaporation, even with samples that contain water. The cards have areas for writing reference numbers, dates and notes for record-keeping purposes. Most samples can be prepared as they would for traditional salt plates.
Product Detail
Useful for qualitative IR transmission analysis of prganic liquids, materials soluble in organic solvents, semisolids and pastes, the card's microporous substrate permits rapid solvent evaporation-even with samples that contain water. Most samples can be prepared for these cards just as they would for use with traditional salt plates. When preforming an analysis, samples can be ratioed against an empty sample card. Two substitutes are available: polyethylene (PE) and polytetrafluoroethlyene (PTFE), and each card contains two cample sites. Samples can be dropped or smeared onto the card substitute, allowed to evaporate and then analyzed. The cards have areas for writing reference number, dates, and notes for record-keeping purposes.
Applications
Organic liquids
Solvents
Pastes
Oils
Semisolids
Features
Microporous sample substrate is chemically resistant and is nonlygroscopic
Requires no desiccated storage
Cards fit easily into most Nicolet FT-IR spectrometers
ST-IR Card 0020-300 is composed of a microporous ployethylene (PE) substrate
Useful in the 4,000-400 cm-1 range, except for the 3,000-2,800 cm -1 aliphatic region
Can be used at temperatures up to 90° C for short durations
ST-IR Card 0020-031 is composed of polytetrafluoroethlyene (PTFE) substrate
Provides a clean background from 4,000-1,400 cm-1 , making it useful for spectral interpretation within the aliphatic C-H stretching region
Can be used at temperatures up to 200° C for short durations
