Ahstract-As to obtain whichever related information about the molecular formula, there are numerous of mass spectrometry applications accessible either web-based or windows-based systems as to calculate the isotope patterns.Additionally, most of the applications are capable to display the mass spectrum as to gain related information on molecules and the particular relative intensity. We have developed TIG as an alternative towards isotope pattern calculator, reinforcing the concept of calculating isotope pattern by using the Cartesian Products. In this paper, we provide an evaluation result for the isotope pattern calculator; Theoretical Isotope Generator (TIG). It is also shown from the evaluation that TIG provides an insight of the related field as well as what should be possessed to be an ideal isotope pattern calculator principally for educational purposes.

Nowadays, photocopiers are commonly available as part of the reprinting or duplication of documents particularly reference books. Therefore, it could be a major setback for the publishers and the authors to retail the books to the readers. Since the field of photometry and colorimetry are advancing in terms of research, it is discovered that the colours comprise of luminance values that are analogous to grayscale intensities ranging from white to black. By exploiting the luminance from the colour properties, grayscale photocopying is greatly discouraged when the grayscale printed copies or grayscale photocopies are scarcely visible of the contents.
