Automated Clean-up for Mineral Oil (Hydrocarbon Oil Index) Analysis using the Agilent 7696A Sample Prep WorkBench
نویسنده
چکیده
Mineral oil (or Hydrocarbon oil) in water samples is determined by liquid-liquid extraction, followed by a clean-up step on Florisil, and GC-FID analysis. Using the Agilent 7696A Sample Prep WorkBench system, drying and clean-up of samples obtained after liquid-liquid extraction can be automated. High recoveries and excellent reproducibility are obtained for the mineral oil fraction, while the clean-up step is very efficient. The extracts are analysed by GC-FID. In combination with low thermal mass (LTM) – GC, an automated high throughput method is obtained. Automated Sample Preparation

Automated Clean-up of PCB extracts from Waste Oil using the Agilent 7696A Sample Prep WorkBench
Solid waste, including petroleum based waste oils, transformer oil or mineral oil are screened for the presence of polychlorinated biphenyls (PCBs). The analysis is typically performed by GC-ECD or GC-MS after clean-up using column chromatography, solid phase extraction (SPE), or dispersive solid phase extraction (d-SPE). Clean-up on silica or acidified silica removes polar constituents that ca...

An automated method for esterifying fatty acids in canola oil samples is presented. Using the Agilent 7696A Sample Prep WorkBench, a side-by-side comparison was undertaken comparing a manual method employing automatic pipettors to a method developed for this automated system. Using the Agilent 7696A Sample Prep WorkBench, preparation of 10 samples resulted in 3% RSD for both an acid-catalyzed a...
متن کاملAnalysis of bisphenol A leaching from baby feeding bottles
Bisphenol A can leach out from the plastic surfaces of food containers and has been detected in various matrices such as plasma, urine and groundwater. Bipshenol A is an endocrine disruptor, which can mimic the body’s own hormones such as estrogen and may lead to negative health effects. In this Application Note, we describe a method to quantify bisphenol A and a structurally similar analog bis...
