Knowledge graph centered on Cuticular hydrocarbon extraction and GC-FID analysis of sweat bees (Halictidae) with 31 nodes and 135 connections. Top connected: Unknown, Bombus, Bombus terrestris, Bombus appositus, B. appositus.
Description
Extraction of cuticular compounds from individual bee specimens using n-pentane solvent followed by gas chromatographic analysis with flame ionization detection for chemical profile characterization. Includes compound identification via GC-MS and structural elucidation using mass spectral libraries.
Typical Equipment
- n-pentane (Uvasol, 99.5%, Merck, Germany)
- nitrogen stream
- Agilent 7820 A Series gas chromatograph
- DB-5 MS capillary column
- flame ionization detector
- HP 6890 series gas chromatograph-mass spectrometer
- AMDIS 2.71 software
- NIST11 library
- solid-phase extraction equipment
- dimethyl disulfide (DMDS)
Output Measurements
- cuticular chemical profiles
- relative compound abundances
- compound identifications
