A wide variety of documents are routinely submitted to our laboratory for analysis on equipment including the: Another service offered is the intercomparison of inks using Thin Layer Chromatography (TLC).
Using this process allows for the accurate discrimination of ink formulas and reduces the possibility of false matches of ink samples from different sources or incorrect differentiation of ink samples with a common origin.

Chemical analysis evaluates composition and p H; physical analysis measures gloss, strength, color.
Organic analysis detects carbon-based traces of plants and organisms; while inorganic analysis identifies mineral evidence in pigment and ink.
These tools are used, alone or in combination, to characterize the properties of paper in a number of ways.
For example, a qualitative analysis shows what materials are in the paper, fiber, ink; quantitative analysis measures how much.
This Atlas consists of type specimens and dates of production of all typewriter typefaces from about 1920.Each of these approaches provides a set of facts about an artifact's condition, age or origins.The method of choice for any given situation is determined by several factors, including: the objectives of the investigator (authentication, preservation, personal curiosity); the relative value of the paper (historically, legally, personally); and whether the information gained from destructive testing will outweigh the loss of material samples.The Atlas is used as an aid in typewriter comparisons by typestyle .It is the most comprehensive reference collection available and is up dated on a regular basis.
