First you set the Soxhlet extractors up on individual heating mantles or baths. Next, tubing is individually attached to each of the condensers. There are dozens of tubes to deal with, and multiple heating mantles to monitor. The problem with this arrangement is that in the end, you have spent more time assembling and monitoring your apparatuses than performing the actual chemistry. To conserve valuable bench space, all samples are arranged in a circle and the instrument rotates allowing each sample to be accessed from the front. Individual condensers are connected to the centrally located water manifold through quick disconnect fittings.

METHOD 23—DETERMINATION OF POLYCHLORINATED DIBENZO-P-DIOXINS AND POLYCHLORINATED DIBENZOFURANS FROM STATIONARY SOURCES 1. Applicability and Principle 1.1 Applicability. This method is applicable to the determination of polychlorinated dibenzo-p- dioxins (PCDD's) and polychlorinated dibenzofurans (PCDF's) from stationary sources. 1.2 Principle. A sample is withdrawn from the gas stream isokinetically and collected in the sample probe, on a glass fiber filter, and on a packed column of adsorbent material. The sample cannot be separated into a particle vapor fraction. The PCDD's and PCDF's are extracted from the sample, separated by high resolution gas chromatography, and measured by high resolution mass spectrometry. 2. Apparatus 2.1 Sampling. A schematic of the sampling train used in this method is shown in Figure 23-1. Sealing greases may not be used in assembling the train. The train is identical to that described in section 2.1 of Method 5 of this appendix with the following additions: Method 23 8/3/2017 2.1.1 Nozzle.

First, a discussion on both conventional Soxhlet as compared with other conventional extraction techniques and some minor improvements of the former for speci®c applications is done. Secondly, a critical comparison of conventional Soxhlet with the new extraction techniques such as supercritical ¯uid extraction, microwave-assisted processes and microwave-assisted solvent extraction shows the reasons why major, recent improvements of this technique (namely Soxtec1 System HT, Soxwave-100 and focused microwave-assisted Soxhlet extraction) have been proposed, aimed at overcoming most of the shortcomings of conventional Soxhlet and converting it into an updated tool for leaching which competes advantageously with the most recent alternatives in the extraction ®eld. # 1998 Elsevier Science B.V.

  • Evaluation of Extraction Methods for Recovery of Fatty Acids from Marine Products
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Universidade do Algarve Master thesis of EMQAL project Evaluation of Extraction Methods for Recovery of Fatty Acids from Marine Products Liping Xiao Supervisor: Svein Are Mjøs, Nofima Ingredients, Bjørn Grung, University of Bergen February 2010 Abstract The extraction efficiency of Soxhlet, acid hydrolysis and Bligh and Dyer were evaluated by using direct methylation on extracts and residues for calculating the mass balance of fatty acids for eight marine powders (fishmeals, krillmeals, cod filet, salmon filet and herring roe). The results show that Soxhlet gave lowest extracted fatty acid content, especially for the samples which contain a high amount of phospholipid. Acid hydrolysis and Bligh and Dyer extract gave comparable extracted fatty acid contents with direct methylation. The mass balance of fatty acids in extract and residue is close to 100% for the three extraction methods which indicate that fatty acid was not lost during the extraction procedures. The difference of extracted fatty acids is mainly due to the different extracting efficiency. The gravimetric lipid has limited correlation with total fatty acids, especially for Soxhlet. Analyses of the fatty acid profiles showed that the Soxhlet extracts were different from the others. Extracts from the acid hydrolysis and Bligh and Dyer methods had similar fatty acid profiles as the direct methylation method. The precision of fatty acid analysis by direct methylation method for marine powders were also validated. The coefficient of variation was 5.11% for solid samples and 1.21% for liquid sample. Key words: direct methylation, one-step methylation, fatty acids, Soxhlet, acid hydrolysis, Bligh and Dyer Table of Contents List of Abbreviations………………………………………………………….
