Both atmospheric pressure chemical ionization (APCI) (58, 68, 69) and electrospray ionization (ESI) (27, 70) have been employed; these ionization techniques provide robust methods of identi cation and quanti cation of HAAs, when stable isotopically labeled internal standards are employed in the assay Both triple quadrupole (58, 69) and ion trap (71) mass spectrometers have been used to measure HAAs in cooked foods When operated in the selected reaction monitoring (SRM) scan mode, tandem MS instruments can detect HAAs at amounts of <1 picogram (27) The tandem SPE method devised by Gross (51, 52), followed by LC-ESI-MS/ MS, provides the most sensitive method of quanti cation of HAAs A limit of quanti cation (LOQ) of 30 parts per trillion (ppt or pg/g) was reported for a number of HAAs in cooked meats, when 1- to 2-g quantities of cooked meat was assayed by this method (27).

The HPLC-based uorescence or UV detection is generally 3- to 10-fold less sensitive than that of the LC-ESI-MS/MS assay (53, 64) The API product ion spectra of HAAs have been characterized In the positive ionization mode, HAAs of the AIA series undergo a principal fragmentation, by APCI or ESI, at the N-methylimidazole moiety ([M + H]+ [M + H CH3]+) to produce radical cation species (5, 27, 58, 69, 72) These species can then undergo further fragmentation of the pyrazine or The HPLC-based uorescence or UV detection is generally 3- to 10-fold less sensitive than that of the LC-ESI-MS/MS assay (53 64) The API product ion spectra of HAAs have been characterized.

However, other workers have demonstrated that HPLC-based methods could offer a simpler analytical alternative to the use of GC/MS, particularly for lcoholic beverages. Herbert et al. (53) developed a simple, rapid, and cost-effective method for the analysis of ethyl carbamate in wine brandy, forti ed wines, and table wines, using HPLCFLD. To achieve the required selectivity, a uorescent derivative of ethyl carbamate was prepared from the reagent 9-xanthydrol according to the scheme given in Fig. .Related: Java QR Code Generating Image, Create QR Code Word Data, Excel QR Code Generating Image

Paint Barcode In Visual Studio .NET Using Barcode maker for ASP . The water-soluble 3MCPD was extracted into saline solution and then partitioned into diethyl ether using a solid-phase extraction technique based on iatomaceous earth. Dried and concentrated extracts were treated with HFBI to convert 3-MCPD to the corresponding HFB diester (see Fig. 2.6.3) prior to analysis by GC and MS. Quanti cation was by a stable isotope internal standard method using deuterium-labeled 3-MCPD (3-MCPD-d5) added to the sample prior to extraction. The method was suitable for the quanti cation of 3-MCPD at concentrations of 10 g kg 1 and was adopted as an AOAC First Action Of cial Method. The three main advantages of this approach were: (i) high sensitivity resulting from the formation of a GC volatile 3-MCPD derivative, (ii) high speci city associated with mass spectrometric detection at higher mass, and (iii) accurate quanti cation from the use of a stable isotope internal standard. The procedure of Brereton et al. (46) has subsequently been modi ed and extended to the analysis of MCPDs and/or DCPs. Nyman et al. (48) optimized a method for the analysis of 1,3-DCP in soy sauces using 10% diethyl ether/ hexane to isolate the dichloropropanol at the solid-phase extraction stage. The mean recovery of 1,3-DCP from spiked test samples was 100% with a relative standard deviation of 1.32%: the method limits of quanti cation (LOQs) was 0.185 g kg 1. Xu et al. (49) added hexane at the initial aqueous extraction stage to remove fat from samples and also reported improved sensitivity and selectivity over electron ionization (EI)-MS when using negative ion chemical.Related: Make UPC-E C# , Creating ISBN .NET , Intelligent Mail Creating Word

More important, MS offers unique speci city that no other technique can For example, Figure 171 shows the comparison of the LC/MS and LC/UV data It is very dif cult to pinpoint exactly which peak is the peak for the compound of interest Based on peak height, the peak at 372 minutes would be selected in frame B However, MS data indicate that the peak at 372 minutes does not have the right mass If we take retention time as a guide that eliminates the peaks at 372 and 382 minutes, three possibilities exists: 255, 265, and 274 minutes If the right peak were chosen, the small size of the peak would make it dif cult to provide accurate quantitative information On the other hand, LC/MS can easily identify which peak is correct We can see from Figure 17.
