Ion trap mass spectrometer

Manufactured by Bruker

Sourced in Germany, France

The Ion Trap mass spectrometer is a type of mass spectrometer that uses an electric field to trap and analyze ions. It is designed to isolate, store, and detect specific ions based on their mass-to-charge ratio. The core function of the Ion Trap mass spectrometer is to provide high-sensitivity and high-resolution mass analysis capabilities for various applications in analytical chemistry, life sciences, and materials science.

4 protocols using ion trap mass spectrometer

Prebiotic Reaction Analysis by NMR and MS

Check if the same lab product or an alternative is used in the 5 most similar protocols

All prebiotic (anaerobic) reactions were carried out under an inert atmosphere of argon, most often in NMR tubes. Irradiations of decarboxylation reactions in water were realized with a Hanau TG 150 high-pressure mercury arc lamp, generally in Pyrex NMR tubes (transparent from 320 nm). No significant difference was noticed when these reactions were run in quartz UV cells.
NMR spectra were recorded on Bruker AV 500 or AV 400, spectrometer at 500 MHz or 400 MHz for ¹H NMR, at 125 or 100 MHz for ¹³C NMR.
Conversions were calculated from NMR spectrum, as were yields (using THF, 1,4-dioxane or acetic acid as quantitative standard).
Electrospray mass spectra were recorded on an ESI Ion Trap mass spectrometer BRUKER amaZon speed. High Resolution Mass Spectra were recorded on a LTQ Orbitrap XL Thermo Scientific.

Chemicals were commercially available and used as received without further purification unless otherwise noted. Moisture sensitive reactions were carried out under a dry argon atmosphere in flame-dried glassware. Thin layer chromatography was performed on silica gel TLC plates with a fluorescence indicator at 254 nm (Fluka). Flash column chromatography was performed using silica gel 60Å (BDH, 40-63 μm). Mass spectra were obtained on a Bruker Ion-Trap Mass Spectrometer at Cleveland State University MS facility Center. All the NMR spectra were recorded on a Bruker 400 MHz spectrometer using CDCl₃ or DMSO-d6 as the solvent.
Reversed-phase HPLC analysis of compounds was conducted on a Beckman HPLC system with an Auto Sampler. The chromatographic separation was performed on a C₁₈ column (2.0 mm × 150 mm, 5 pm) from Phenomenex (Torrance, CA). The mobile phase was employed for isocratic elution with a flow rate of 0.2 mL/min. The injection volume was 20 μL and the UV detector was set up at 260 nm.
The synthesis procedures of compounds 1-60 are listed below.

A Jasco^® LC-2000Plus Series System (Gross-Umstadt, Germany) was used for LC-DAD analysis. LC-MS measurements were performed on an Agilent 1100 Series System, equipped with binary high-pressure mixing pumps, with an autosampler, a degasser module, a 1100 series photodiode array (PDA) detector (Agilent Technology, Germany), and an ion-trap mass spectrometer with an electrospray ionization interface (Bruker Daltonics, Bremen, Germany). A Bruker Daltonics microTOF spectrometer focus was used for high-resolution electrospray mass spectrometry (positive mode). NMR analyses were acquired on AMX 400 and DMX 600 Bruker spectrometers with cryoprobes. The offline ECD and ORD spectra were recorded on a Jasco J-715 spectropolarimeter, and evaluated with SpecDis_164^{24 (link),25}. A Shimadzu UV-1800 spectrophotometer was used to perform offline UV measurements in triplicate. A Jasco P-1020-polarimeter operating with a sodium light source (λ = 589 nm) was used for the measurement of optical rotations. The mechanical shaker operating at the frequency of 160 RPM (rotations per minutes) was from Bottmingen (Switzerland).

Mass spectrometry (MS) analyses were performed on a Ion trap mass spectrometer with an electrospray ionization (ESI) interface (Bruker Daltonics, Wissembourg, France) operating in negative ion mode. The samples of additives were dissolved in methanol and then filtered through a polymer membrane with a pore diameter of 0.45 µm. The injection of samples was made by syringe. The following conditions of the ESI interface were used: drying gas flow, 8.0 L min⁻¹; nebulize pressure, 3 bars; gas drying temperature, 200 °C; capillary voltage, 5000 V; fragmentor voltage, 1 V.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
