For more challenging cleanings, solutions made of beeswax and carbon tetrachloride can be used. One of the biggest challenges in treating encaustic paintings is identifying the different waxes used to determine the appropriate treatments. Infra-red photography and gas chromatography can be used to identify the various types of waxes. [22]
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [ 1 ]
Little Machine Constructed by Minimax Dadamax in Person (Von minimax dadamax selbst konstruiertes maschinchen) (1919–20) is a mixed-media work of art by the German dadaist and surrealist Max Ernst. It is probably the most famous example of a series of Ernst's works that were based on diagrams of scientific instruments.
For example, GC Image was the first software developed for two dimensional gas chromatography. Some software [15] packages are used in addition to the normal GC (or GC-MS) packages while others are built as a complete platform, [16] [17] controlling all aspects of the analysis. The new and different way of presenting and evaluating data offers ...
This is a series of original works of art and screen prints. He was inspired by memories of the technique of spin painting which he saw as a child on the BBC's Blue Peter. [1] Lawrence Stafford. During the late 1960s developed a spinning rotating machine on which he attached raw canvas and sprayed acrylic paint while the drum spun.

Gas chromatography-olfactometry (GC-O) is a technique that integrates the separation of volatile compounds using a gas chromatograph with the detection of odour using an olfactometer (human assessor). [1] It was first invented and applied in 1964 by Fuller and co-workers. [2]
Gas chromatography–vacuum ultraviolet spectroscopy (GC-VUV) is a universal detection technique for gas chromatography. [1] VUV detection provides both qualitative and quantitative spectral information for most gas phase compounds. GC-VUV spectral data is three-dimensional (time, absorbance, wavelength) and specific to chemical structure.
