Evaluation of pesticide adsorption in gas chromatographic injector and column
(Química Nova, 2018)
Interpretation of matrix chromatographic-spectral data modeling with parallel factor analysis 2 and multivariate curve resolution
(Elsevier Science, 2019-10)
The use of edible films to release antimicrobial constituents in food packaging is a form of active packaging that contributes to extend the shelf-life of a product and provides microbial safety for consumers. A number of ...
Sulfanilic acid-modified chitosan mini-spheres and their application for lysozyme purification from egg white
(American Chemical Society, 2018-03)
A cation exchange matrix with zwitterionic and multimodal properties was synthesized by a simple reaction sequence coupling sulfanilic acid to a chitosan based support. The novel chromatographic matrix was physico-chemically ...
Assessment of Matrix Effect in Quantitative Milk Analysis for Pyrethroids Based on GC-MS/MSAssessment of matrix effect in quantitative milk analysis for pyrethroids based on GC-MS/MS

2-MERCAPTOBENZOTHIAZOLE CLAY AS MATRIX FOR SORPTION AND PRECONCENTRATION OF SOME HEAVY-METALS FROM AQUEOUS-SOLUTION
(Elsevier Science BvAmsterdamHolanda, 1995)
Chromatographic matrix based on hydrogel-coated reticulated polyurethane foams, prepared by gamma irradiation
(Pergamon-Elsevier Science Ltd, 2017-12)
Novel chromatographic materials for protein purification with high adsorption capacity and fouling resistance are highly demanded to improve downstream processes. Here, we describe a novel adsorptive material based on ...
Second-order chromatographic photochemically induced fluorescence emission data coupled to chemometric analysis for the simultaneous determination of urea herbicides in the presence of matrix co-eluting compounds
(Royal Society of Chemistry, 2014-08)
This paper presents a novel approach for the simultaneous determination of isoproturon, rimsulfuron and monuron, three widely used urea-derivative herbicides, in interfering environmental samples, combining the advantages ...
Matrix Effect Assessment of an Ion Chromatographic Method to Determine Inorganic Anions in Wastewater
(2018-07-01)
Inorganic anion monitoring is essential for bioreactor operation and is related for pollution control or energy and products recovery. However, there is a lack of studies validating methods for inorganic anions analyses ...
A new modeling strategy for third-order fast high-performance liquid chromatographic data with fluorescence detection: Quantitation of fluoroquinolones in water samples
(Springer Heidelberg, 2015-02)
Matrix augmentation is regularly employed in extended multivariate curve resolution-alternating least-squares (MCR-ALS), as applied to analytical calibration based on second- and third-order data. However, this highly ...
