An easy and fast method using electrospray ionization mass spectrometry for determination of the stability constants (logK s ) of different metal-ion complexes with crown and lariat crown ethers has been developed. This method has been verified with known logK s by using either excess crown ether or

A new candidate reference method is presented for the determination of thyroxine in serum. The method is based on isotope dilution-liquid chromatography/tandem mass spectrometry using electrospray for ionization. The internal standard used was 13 C 6 -thyroxine, sample pretreatment consisted of prot
## Abstract Hyperhomocysteinemia is a risk factor for different diseases. Several methods have been developed to analyze homocysteine and the immunometric ones, although expensive, they are in widespread use. A rapid LCβMS/MS method for homocysteine assay has been developed for the application of l
Isotope dilution-gas chromatography/mass spectrometry (ID-GC/MS) and isotope dilution-liquid chromatography/tandem mass spectrometry (ID-LC/MS/MS) methods have been developed for an determination of triiodothyronine (T3) in serum and their potential as candidate reference methods investigated. In bo
## Abstract Flavonol 3,7βdiβ__O__βglycosides were investigated by negative ion electrospray ionization tandem mass spectrometry using a quadrupole linear ion trap (LIT) mass spectrometer. The results indicate that the fragmentation behavior of flavonol 3,7βdiβ__O__βglycosides is substantially diffe
