A non-aqueous fluidic system for extracting, filtering and concentrating lipid biomarkers from geological samples includes a sample input for receiving a sample, a combined comminution-extraction unit, a filter in fluid communication with the container, and a concentrator operable to receive the solvent phase from the filter and to concentrate lipid extracts for further analysis. The combined comminution-extraction unit has a container into which the received sample is introduced, a port through which one or more organic solvents are introduced into the container for mixing with the sample to thereby extract lipids into an organic phase, and a comminutor configured to rotate in the container to pulverize the sample to a uniform, reduced particle size and comprising a sonicator configured to agitate and disperse the sample into the one or more organic solvents.

Extractor for chemical analysis of lipid biomarkers

In one embodiment, a plurality of images is received. The plurality of images are frames of a video file. A user requests for a thumbnail picture representative of the plurality of images. The plurality of images are filtered to obtain a set of images. The filtering can be based on a blurriness of the image, whether an image is near a scene transition, an amount of text depicted in the image, or a color level of the image. Valence scores may be determined for one or more of the images in the set of images. Valence scores are based on determining values of characteristics of an image that can predict user responses to the image. A first image from the set of images is selected based at least in part on the valence score of the first image. The first image is sent for display.
