A lubricating composition comprises a base oil and between 10 ppm and 1000 ppm by mass of a viscosity modifier, the viscosity modifier comprising a polymer having a number average molecular weight greater than 500,000. The polymer's side-chains may be branched or unbranched. The polymer is preferably selected from the group consisting of polyolefin, poly alpha olefin, poly internal olefin, ethylene-propylene copolymers, ethylene-propylene-diene copolymers, ethylene-propylene-acrylate copolymers, ethylene-propylene-methacrylate copolymers, ethylene-propylene-aromatic copolymers, ethylene-propylene-diene-acrylate copolymers, ethylene-propylene-diene-methacrylate copolymers, and combinations thereof.

Sample preparation can be a tedious and time consuming task. For example, MALDI imaging of tissue samples can require the tedious process of hand or robotically spotting solutions containing chemical species referred to as “matrix” onto a tissue sample prior its mass spectral analysis. Provided is a process for preparing a sample comprising immersing a solid support that has a surface comprising a first part that is more hydrophilic than a second part into a target compound solution, wherein the target compound is deposited primarily onto the more hydrophilic part; and/or applying and evaporating the target compound solution onto the substrate to produce the pre-coated substrate. A tissue or other sample may then be placed on the substrate for analysis.
