This closely agrees with the fact that the seals from Indus Valley style from Ur, Kish and Tell Asmar and other sites fall within the range of 2500-1500 B. When a group or type of objects are found together under circumstances suggesting contemporanity they are said to be associated.It is nearly always association with other phenomena that gives a first clue as to the use, the age and chronological attribution of a potential datum, but age at least may sometimes be inferred from position in a geological deposit or a layer of peat.Detection of fluorine in solids, gases & liquids are possible using this technique as the apparatus is equipped with a gas, liquid syringe and solid boat module.Fluoride analysis sensitivity can reach 0.1 ppm depending upon sample type and sample introduction.Once a type has been classified by the aid of its context further specimen of the same type, even when found in isolation, can be assigned their place in terms of dates.

According to this method, the upper deposits are younger and the lower deposits are older.For example, beads closely resembling those from the temple repositories at Cnoss and dating from C.1600 B.C were found in a late context (Period V) at Harappa. By noting the association of these beads it has been possible to trace a archaeological datum line across Indian sub-continent and Mesopotamia. Intertek laboratories provide a range of analytical testing services for the measurement and characterization of fluorine and fluoride in solids, liquids and gases.The Intertek USA laboratories provide fluorine analysis using a COSA AQF-100 combustion furnace coupled to a Dionex ICS 2000 ion-chromatograph.
