Introduction

The Q Exactive Focus is a state-of-the-art mass spectrometer that provides high sensitivity, accuracy, and resolution for the analysis of complex biological samples. It is designed for proteomics, metabolomics, lipidomics, and other applications in the life sciences. The instrument uses Orbitrap technology to detect and quantify molecules based on their mass-to-charge ratio (m/z).

Orbitrap Technology

The Q Exactive Focus uses Orbitrap technology, which was invented by Alexander Makarov at Thermo Fisher Scientific in 1999. It consists of an electrostatic trap that captures ions and a cylindrical electrode that induces their oscillation. The frequency of the oscillation is proportional to the mass-to-charge ratio of the ion, allowing for accurate mass determination. The Orbitrap technology provides high resolution, mass accuracy, and dynamic range for the detection of small molecules, peptides, and proteins.

Specifications

The Q Exactive Focus has a mass range of 50-6,000 m/z and a resolving power of up to 140,000 at m/z 200. It can acquire spectra at a rate of up to 12 Hz, enabling high-throughput analysis. The instrument has a linear ion trap for precursor ion selection and fragmentation, and a high-energy collision dissociation (HCD) cell for peptide sequencing. The Q Exactive Focus also has an optional ETD (electron transfer dissociation) module for protein characterization.

Applications

The Q Exactive Focus is used in a variety of applications in the life sciences, including:

Proteomics

Proteomics is the study of proteins and their functions in biological systems. The Q Exactive Focus can identify and quantify proteins in complex mixtures, such as blood or tissue samples. It can also detect post-translational modifications, such as phosphorylation or glycosylation, which are important for protein function.

Metabolomics

Metabolomics is the study of small molecules, such as metabolites, in biological systems. The Q Exactive Focus can identify and quantify metabolites in various biological matrices, such as urine or plasma. It can also provide information on metabolic pathways and disease biomarkers.

Lipidomics

Lipidomics is the study of lipids, such as fatty acids and phospholipids, in biological systems. The Q Exactive Focus can identify and quantify lipid species in various biological matrices, such as brain tissue or adipose tissue. It can also provide information on lipid metabolism and disease biomarkers.

Advantages

The Q Exactive Focus has several advantages over other mass spectrometers:

Sensitivity

The Q Exactive Focus has high sensitivity, allowing for the detection of low-abundance molecules in complex samples. This is important for biomarker discovery and disease diagnosis.
