SIMS in general refers to four instrumental categories according to their operation; static, dynamic, quadrupole, and time-of-flight, TOF. In essence it is a technique with a large resolution on a plethora of chemical elements and molecular structures in an essentially non destructive manner. An approach to OHD with a completely new rationale suggests that refinement of the technique is possible in a manner which improves both its accuracy and precision and potentially expands the utility by generating reliable chronological data.

In Rhodes, Greece, under the direction and invention of Ioannis Liritzis,  the dating approach is based on modeling the S-like hydrogen profile by SIMS, following Fick's diffusion law, and an understanding of the surface saturation layer see Figure. In fact, the saturation layer on the surface forms up to a certain depth depending on factors that include the kinetics of the diffusion mechanism for the water molecules, the specific chemical structure of obsidian, as well as the external conditions affecting diffusion temperature, relative humidity, and pressure.
This latest advance, the novel secondary ion mass spectrometry—surface saturation SIMS-SS , thus, involves modelling the hydrogen concentration profile of the surface versus depth, whereas the age determination is reached via equations describing the diffusion process, while topographical effects have been confirmed and monitored through atomic force microscopy.

Several factors complicate simple correlation of obsidian hydration band thickness with absolute age. Temperature is known to speed up the hydration process. Thus, artifacts exposed to higher temperatures, for example by being at lower elevation , seem to hydrate faster. As well, obsidian chemistry, including the intrinsic water content, seems to affect the rate of hydration.
Once an archeologist can control for the geochemical signature of the obsidian e.

Water vapor pressure may also affect the rate of obsidian hydration. The first step concerns the calculation of a 3rd order fitting polynomial of the SIMS profile eq. The second stage regards the determination of the saturation layer, i. The whole computing processing is embedded in stand-alone software created in Matlab version 7.
