3. A phenomenon or feature not originally present or expected and caused by an interfering external agent, action, or process, as an unwanted feature in a microscopic specimen after fixation, in a digitally reproduced image, or in a digital audio recording.
4. An inaccurate observation, effect, or result, especially one resulting from the technology used in scientific investigation or from experimental error: The apparent pattern in the data was an artifact of the collection method.

[Latin arte, ablative of ars, art; see art1 + factum, something made (from neuter past participle of facere, to make; see dhē- in Indo-European roots).]

This approach is evident in her work as the founder of TAMI, the Texas Archive of the Moving Image, an on-line archive that digitizes film and video and makes it available on-line, but does not house the artifactual materials, leaving them with the original owners and educating them on the basics of proper storage.

This labeling strategy provides several advantages over conventional approaches : 1) compounds arising from biosynthesis (experimental and control) have a unique isotopic signature and all unsigned artifactual signals can be removed from the dataset (usually the largest portion of the dataset); 2) sample-to-sample variance from sample extraction and preparation is minimized because the control and experiment are combined into a single sample; 3) measurement of both the molecular weight and the exact number of carbon atoms in each molecule provides extremely accurate molecular formulas; and 4) as the protocol uses a central biochemical point of reference embedded in every sample, relative concentrations of all metabolites are easily determined.
