HPLC [17, 18] and UPLC [11] coupled with tandem mass spectrometry were also used.
Thermal gravimetric analysis and mass spectrometry were employed to identify the degraded volatile products.
Leakage rates determined from mass spectrometry were about 4.57 * 10− 7 L/s at 750 °C.
The sequential extraction EPA 3200-Method and the determination technique based on capacitively coupled microplasma optical emission spectrometry were checked.
Protein extraction, digestion, iTRAQ labeling, and mass spectrometry were conducted using protocols from previous paper (Xing et al. 2014).
Scanning electron microscopy, X-ray photoelectron spectroscopy and Raman spectrometry were used for the surface examination.
SDS PAGE, HPLC and MALDI-TOF mass spectrometry were undertaken to determine the purity and molecular weight of rhGLPs.
SEM/EDS, STEM/EDS, XRD and Infrared Spectrometry were performed to characterize before and after reaction the solid phase.
Fourier transform infrared (FT-IR) spectrometry and Raman spectrometry were used to obtain information about the functional groups.
Non-Rutherford backscattering and Rutherford backscattering spectrometry were used to analyze changes in the carbon depth profiles.
Raman spectrometry, X-ray photoelectron spectroscopy, scanning electron microscopy, and energy dispersive spectrometry were used to characterize these modified CNT.
