TLDR
Butterworth low-pass filters, frequently used to improve signal-to-noise ratios in chromatographic instrumentation, are chosen for their frequency domain characteristics; their time domain response may introduce spurious peaks which are eliminated by use of the Bessel filter which provides improved chromatography response.

On-line fractionation and identification of diesel fuel polycyclic aromatic compounds by two-dimensional microbore high-performance liquid chromatography/capillary gas chromatography

I. L. Davies, +3 more
- 01 Feb 1988 - 
TL;DR: In this article, a two-dimensional model of HPLC/GC retention indexes is used to identify two-to four-ring polycyclic aromatic compounds in diesel fuel, and individual components are resolved by temperature-programmed capillar GC with flame-ionization detection.

Sensitivity improvement of circular dichroism detection in HPLC by using a low-pass electronic noise filter: Application to the enantiomeric determination purity of a basic drug.

Marie Lorin, +4 more
- 01 Feb 2007 - 
TL;DR: The quality control of chiral drugs requires the determination of their enantiomeric purity and circular dichroism (CD) spectroscopy is gaining increasing importance in pharmaceutical analysis because of the commercially available CD detector in liquid chromatography.

An evaluation of the negative ion mass spectra of electron‐capturing derivatives of the biogenic trace amines I—phenylethylamine

David A. Durden
- 01 Jun 1991 - 
TL;DR: In this article, a series of fluorinated derivatives have been examined for their suitability of use for quantification of biogenic trace amines, in particular phenylethylamine, in biological samples at the picogram (femtomolar) level using negative ion mass spectrometry.
