matrix spike sample
Jamie Humphries, Product Manager, Internal Standard Retention Time and Peak Width Diagnostic Chart. The analytes selected as surrogates mimic the behavior of the target analytes throughout sample preparation and analysis, but are not normally found in the environment. The surrogate recoveries assess sample matrix interference effects and laboratory performance. Matrix Spike Duplicate – with compounds spiked into it at the same level as the Matrix Spike; Unknown – a sample with unknown amounts; Under QAQC tab of the Master/Local Method the concetrations of the spikes compounds must be entered in the grid for the MS and MSD tab.

The MS is analyzed as a method performance assessment by measuring the effects of interferences caused by the specific sample matrix. There must be one of each SAMPLE TYPE, but each one must have the sample SAMPLE  ID text in their individual grid cell. 520 0 obj <>/Filter/FlateDecode/ID[<8E56BE2E97A22991D3F24F72F16AB08B><20B63590BC933944AEA6DA4E00B1CAA9>]/Index[496 54]/Info 495 0 R/Length 113/Prev 100203/Root 497 0 R/Size 550/Type/XRef/W[1 2 1]>>stream Making changes in to the multiple peaks in a compound (Answer to a “Ask A Guru” question) →, HRAM Analytical Methods for Screening and Quantitation on Q Exactive Series, HRAM Analytical Methods for Screening and Quantitation on a Q Exactive Focus, A tutorial on how to setup and process High Resolution Accurate Mass (HRAM) screening and quantitation data sets in TraceFinder 4.1, FreeStyle tutorial: Automated Peak Detection settings, Freestyle tutorial: Comparing Chromatograms, Matrix Spike – with compounds spiked into it at a known level, Matrix Spike Duplicate –  with compounds spiked into it at the same level as the Matrix Spike.

When the batch is processed the data for recovery will be calcuated and a MS/MSD Report can be generated that displays the information about this experiment. To set up the experiment the chemist needs three sample types. Surrogate spikes of known concentrations are added to primary samples, which are then analyzed and reported. Under QAQC tab of the Master/Local Method the concetrations of the spikes compounds must be entered in the grid for the MS and MSD tab. Laboratory Control Sample Duplicate (LCSD): A laboratory control sample duplicate (LCSD) is an additional replicate of the LCS. Helping You Understand Quality Assurance-Quality Control Samples. Thanks to Gail Harrison for her suggestion on a blog post. This allows for the chemist to calcualte a recovery of of the compounds contained in the unknown sample. spiked and analyzed, then a matrix spike & matrix spike duplicate on the same sample in a 20-sample batch does NOT meet that requirement.
