After changing the pre-injection delay from 500ms to 0ms and the injection speed from 50uL/s to 5uL/s these poor injections have disappeared.

some memory effect between samples. It is most notable between the PNZ and DSW-ANT working standards, which span a wide range of isotope ratios. In processing the data we will only use results acquired after the first injection. For the working standards that means that we'll use the mean of the second and third injection. Since we are only performing two injections per sample in this data set, we'll only be using the value of the second injection. As we have replicate analyses incorporated into the sequence, we will still have a good estimate of the analytical uncertainty of the measurements. https://static1.squarespace.com/static/59e2934e4c326d03999842ee/t/5dd72809f43c174dfb0ee3c1/1574381590702/EA_021_N_quant_i.gif Protocols and Methods https://static1.squarespace.com/static/59e2934e4c326d03999842ee/t/5ecd9922ad765166586e1a94/1590532402444/37%2B25_H_4_clean.GIF Protocols and Methods https://static1.squarespace.com/static/59e2934e4c326d03999842ee/t/5eceffb5f92e96799c8341fa/1590624189473/23_16-linearityplots.GIF Protocols and Methods https://static1.squarespace.com/static/59e2934e4c326d03999842ee/t/5ecd90d795a4d74aea923e69/1590530364726/10%2Bsequencelist_crop.JPG Protocols and Methods Here is an active sequence list.
