Analysis of Analytical Laboratory Services using Nuclear Magnetic Resonance spectrometer (NMR) at Scientific Instruments Center, School of Science, King Mongkut's Institute of Technology Ladkrabang, Thailand

Abstract

This research aims to analyze data on laboratory analysis services using the Nuclear Magnetic Resonance spectrometer (NMR), including the number of service users, number of analyzed samples, and type of service user organization. In addition, the data were analyzed on income, expenses, and net income of analytical services. Data from the fiscal year 2019 to 2023 will be used from the database reporting on laboratory analysis services with NMR. The collected data was classified and analyzed using descriptive statistics. The number of service users was 511 NMR machine users, and 2,134 samples were sent for analysis. The average number of samples for analysis on the Solid-state NMR 400 MHz is 15.40 service forms/year and 44 samples/year. For the Solution-state NMR 500 MHz, the number of service users and the average number of samples for analysis are 86.80 service forms/year and 382.80 samples/year. A total income of 2,375,273.00 baht, consisting of a Solid-state NMR 400 MHz in the amount of 659,003.00 baht and a Solution-state NMR 500 MHz in the amount of 1,716,270.00 baht. For expenses from providing services, a Solid-state NMR 400 MHz and a Solution-state NMR 500 MHz have total costs of 890,924.40 baht and 1,179,010.60 baht, respectively. which were found that 54.04 and 86.85 percent of the total expenses of the Solid-state NMR 400 MHz and Solution-state NMR 500 MHz were maintenance costs for liquid helium refilling. When calculating the net income, it was found that there was a net income of 295,838.00 baht. All analysis results indicate that providing analytical services using NMR instruments still needs more publicity because the major service users are Departments within the institute - within the School of Science.
