On Track for a Truly Green Propolis-Fingerprinting Propolis Samples from Seven Countries by Means of a Fully Green Approach
(2016-12-05)
The production of quality bee products, as well as bee survival itself, depends on the health conditions of the environment, but ironically, harmful solvents are often employed by scientists and traders to monitor the ...
Is Thermogravimetry an efficient alternative to gas chromatography in degree of biodiesel conversion?
(2018-05-17)
This work aims to determine if thermogravimetry could be used to determine the degree of conversion of soybean oil to biodiesel without knowing the amount of ester in the sample, comparing the results with the values ...
A trade off between separation, detection and sustainability in liquid chromatographic fingerprinting
(Elsevier B.V., 2014-08-08)
It is now recognized that analytical chemistry must also be a target for green principles, in particular chromatographic methods which typically use relatively large volumes of hazardous organic solvents. More generally, ...
Fingerprinting Cynara scolymus L. (Artichoke) by Means of a Green Statistically Developed HPLC-PAD Method
(2018-07-01)
The process to develop a chromatographic method for fingerprinting complex matrices should be performed through a multiparameter approach that could lead to the desired separation and save environmental resources such as ...
Determination of quinolone residues in tilapias (Orechromis niloticus) by HPLC-FLD and LC-MS/MS QToF
(Taylor & Francis LtdAbingdonInglaterra, 2009)
Natural deep eutectic solvents as the major mobile phase components in high-performance liquid chromatography—searching for alternatives to organic solvents
(2018-06-01)
Over the past six decades, acetonitrile (ACN) has been the most employed organic modifier in reversed-phase high-performance liquid chromatography (RP-HPLC), followed by methanol (MeOH). However, from the growing environmental ...
An eco-friendly and low-cost method for the quantification of Cefazolin sodium in powder for injectable solution using thin-layer chromatography assisted by digital images
(2017-08-01)
Cefazolin sodium (CFZ) is a semi-synthetic first-generation cephalosporin used for the treatment of infections caused by Gram-positive and Gram-negative microorganisms. Although it is a drug used worldwide, there are only ...
