1. A spectrometer configurable for field analyses of chemical properties of a material, the spectrometer comprising:

a hand-held instrument comprising at least one sensor adapted for providing Fourier transform infrared spectroscopy (FTIR) surveillance and at least another sensor for providing Raman spectroscopy surveillance, and the spectrometer further including a user accessible instruction set for modifying a sampling configuration of the spectrometer.

2. (Canceled)

3. The spectrometer of Claim 1, further including a plurality of user accessible response profiles, each response profile providing the instruction set for modifying the sampling configuration of the spectrometer.

4. A method of determining the most likely composition of a sample by at least two technologies using a spectrometer, the method comprising:

a. obtaining data from the sample by a first technology using the spectrometer, wherein the data comprises a first representation of a measured spectrum obtained by the first technology;

b. determining a precision state of the first representation of the measured

spectrum;

c. providing a first set of library candidates and, for each library candidate, providing data representing each library candidate, wherein the data comprises a representation of a library spectrum obtained by the first technology;

d. selecting a first subset of library candidates by determining a first representation of the similarity of the sample to each library candidate in the first set of library candidates using (i) the first representation of the measured spectrum; (ii) the precision state of the first representation of the measured spectrum; and (iii) the representation of the library spectrum for that library candidate;

e. determining a first most likely composition of the sample based upon the selected first subset of library candidates;
