LECO-courses
FBT1 Elementary course in Combustion analysis for operators
Time 1 day
Theoretical and practical course ´
Theory about the technique, how it works and why you use combustion analysis.
How the instrument is working, sample preparations tools, crucibles, accelerators, samples, applications.
The courses are splitted in C, S and N, O, H (half a day each)
FBT2 Advanced course in combustion analysis. The course is aimed at instrument responsible persons
Time 1 day
The course examines every active part in the instrument and what errors could be caused and how to correct them. It is mainly a pratical course.
FBT3 Linearisation/calibration of a combustion instrument
Time 1 day
Often conclusions are made in respect to matrixes that in fact are non-linearised instruments. This course shows how to linearise and how to calibrate, using CRMs and Gase dose. Then precision is often 2-4 times better after a linearization. The analytical ranges can also be wider
