Spectroscopy

In addition to an empirical formula derived through our CHN/O and Heteroelemental and Metal analyses, Robertson Microlit Laboratories can provide structural information about the the chemical compound.

FT-IR

Our laboratory can offer FT-IR analysis covering the 4000-400 cm-1 infrared region. We use the newest instrumentation Perkin Elmer System 2000 FT-IR and Nicolet Magna-560.

We print out customized FT-IR reports, and tailor data and graphs to your individual needs. We can supply you with analysis data in J-CAMP format for in-house archiving or data modifications.

UV

Robertson Microlit offers our customers a comprehensive, reliable and cost effective UV service, where our experienced staff uses the newest instrumentation.

We provide you with a routine UV-Spectrum scan from 400-200 nm, which can be further expanded into the visible range if necessary.

We report the respective nanometers for UV-maxima, shoulders and plateaus in absorption units (AU). If the molecular weight (MW) is given, we report extinction coefficients (E), otherwise, values as (E1%1cm).

As a general rule, we prepare solutions of 0.5 mg compound in 50 ml spectro grade methanol; we make further solutions if necessary.

Rotation

We use the Perkin Elmer Model 341 Polarimeter which provides measurements at five discrete wavelengths: 589nm, 578nm, 546nm, 435nm, and 365 nm.

Hard copy reports feature experimental data (at least five readings after stability), calculations, and instrument settings and conditions.
