AB  - Fourier transform infrared spectroscopy (FTIRS) can provide detailed information 
      on organic and minerogenic constituents of sediment records. Based on a large 
      number of sediment samples of varying age (0-340,000 yrs) and from very diverse 
      lake settings in Antarctica, Argentina, Canada, Macedonia/Albania, Siberia, and 
      Sweden, we have developed universally applicable calibration models for the 
      quantitative determination of biogenic silica (BSi; n = 816), total inorganic 
      carbon (TIC; n = 879), and total organic carbon (TOC; n = 3164) using FTIRS. 
      These models are based on the differential absorbance of infrared radiation at 
      specific wavelengths with varying concentrations of individual parameters, due to 
      molecular vibrations associated with each parameter. The calibration models have 
      low prediction errors and the predicted values are highly correlated with 
      conventionally measured values (R = 0.94-0.99). Robustness tests indicate the 
      accuracy of the newly developed FTIRS calibration models is similar to that of 
      conventional geochemical analyses. Consequently FTIRS offers a useful and rapid 
      alternative to conventional analyses for the quantitative determination of BSi, 
      TIC, and TOC. The rapidity, cost-effectiveness, and small sample size required 
      enables FTIRS determination of geochemical properties to be undertaken at higher 
      resolutions than would otherwise be possible with the same resource allocation, 
      thus providing crucial sedimentological information for climatic and 
      environmental reconstructions.
