Abstract: A sampling unit is fluidically coupled to a source. The sampling unit is configured for receiving a fluidic sample from the source and chromatographically separating the received fluidic sample. The sampling unit is operated to introduce a test sample into the source. At least a portion of the introduced test sample from the source is received into the sampling unit, and the received portion of the test sample is chromatographically separated in the sampling unit.

Abstract: In some examples, an apparatus may include analyzing a sample, and analyzing at least one reference sample. A determination may be made as to whether the sample includes a library match score. Based on a determination that the sample includes the library match score, the library match score and a retention time may be analyzed to determine similarity between the sample and the at least one reference sample.

Abstract: Compounds useful for forming nucleic acids having the structure of Formula I: Each of R1 or R2 is independently selected from hydrogen, a protecting group, or a phosphoramidite group. R3 is selected from H, F, O—C1-6 alkyl, O-MOE and a removable hydroxyl-protecting group. Q is a heterocyclic base. R4 is a cyclic hydrocarbon. Also disclosed are processes for forming the nucleic acids from the compounds and the nucleic acid products produced.

Abstract: In some examples, deterring a third party from copying a product or process may include scanning code to generate scanned code. Text in the scanned code may be read and/or at least one image in the scanned code may be recognized. The text and/or the at least one image may be analyzed to determine whether the code includes a specified trademark. Based on a determination that the code includes the specified trademark, an indication of authenticity of the code may be generated.

Abstract: In some examples, a filter assembly may include a filter including a first gasket having a first channel adjacent to a first side of the filter and a second gasket having a second channel adjacent to a second side of the filter. The first gasket and the second gasket may include a beveled surface adjacent to the filter. The first channel and the second channel may include a diameter of from about 0.01 mm to about 0.5 mm. A finger tightening system may securely hold the filter without any leaks.

Abstract: In some examples, linear and non-linear range-based plot pane selection may include receiving data that is to be displayed. Based on an increase or a decrease in a size of a range selector, a selection of a range of plot panes may be received from a plurality of available plot panes to display the data. Based on the received selection of the range of plot panes, a display of the data may be generated in plot panes included in the range of plot panes. The size of the range selector may be non-linearly proportional to the available plot panes to display the data.

Abstract: One aspect of the invention provides a method of making a thermal vapor coated article including a chemical vapor deposition of a coating on a surface of the article. The method includes exposing the article to one or more of (i) an inorganic precursor, (ii) an organic molecular precursor, (iii) a precursor to produce oxides or nitrides, or (iv) a combination thereof, wherein the coating is one or more of resistant to adhesion of biomolecules to the coated surface or inert to analytes in contact with the coated surface.
