Reaction Byproduct Quantification & Mass Balance Closure

Polyarc® Supercharges Your Lab

Polyarc is for scientists and engineers who need accurate and reliable tools to analyze samples, quantify impurities, measure yields, and track carbon distribution in reaction products.

Polyarc helps generate the data needed for informed process decisions and accelerated test results.

Polyarc puts you in control – delivering precise data quantification, reducing calibration time, and limiting your overall reliance on standards.

How Does a Polyarc Work?

Due to the response variability of flame ionization detectors (FIDs) – users must determine the response factor of each compound – how much signal is produced per mass of compound injected – through calibration. Accurate calibration lets you convert FID response peak area to the amount of compound present (e.g., g/mL).

Polyarc takes things to the next level – converting the carbon in compounds to methane – making all response factors per carbon the same. This means that when the molecular formula of each compound is known – the quantitation of each compound can be accomplished with a single internal/external standard.

When all compounds are measurable, carbon percentage is determined by the peak area percentage. Unknown carbon concentrations are easily quantized – and mass concentrations can be arrived at from estimates of the C:heteroatom ratios.

Achieve Great Results

Achieving outstanding Polyarc results requires a gas chromatograph (GC) equipped with an FID and suitable inlet (e.g., split/splitless, on-column, PTV). Headspace sampling will NOT work as it leads to vapor-liquid equilibrium fractionation unless total evaporation techniques are employed.

Incorporating a Polyarc into your workflow delivers benefits across the board:

  • Fast analysis
  • No extensive calibration
  • No need for expensive or unavailable standards
  • Carbon mass balance closure on-the-fly (area % = carbon %)
  • Quickly determine purity (area % of target compound = carbon purity %)
  • Quickly determine concentration(s) of impurities
