Hamamatsu Photonics is a worldwide leading manufacturer of opto-electronic components and systems. Among others we offer sensors and systems for spectroscopy (including ultra fast), scientific-grade cameras, beam monitoring solutions, photon counting detectors and systems, photomultipliers, photodiodes, IR detectors. Our experts are looking forward to discuss your needs and specifications in personal meetings.
Hamamatsu offers microchannel plate (MCP) assemblies and electron multipliers as ion detectors coupled to mass analyzers of various types: time-of-flight (TOF), quadrupole, quadrupole time-of-flight (Q-TOF), and double-focusing magnetic sector. Specific products are recommended for each type of analyzer below.
For use as UV light sources for soft ionization methods under vacuum or at standard pressure (e.g., atmospheric pressure photoionization). They emit UV light (115 - 400 nm) that cause minimal fragmentation of biomolecules and other compounds, making it easier to identify molecular weights or to determine amounts of specific ions. Hamamamtsu's deuterium lamps feature very stable light output, a long lifetime, and easy connection to a vacuum system.
Mass analysis based on time-of-flight requires an ion detector with a fast time response. Our microchannel plate (MCP) assemblies designed for TOF-MS have a response time from a few nanoseconds to as fast as 450 ps FWHM. In addition, they are robust and have excellent flatness, which they retain even after long-term use. This MCP flatness ensures a small time jitter; the same type of ions hitting the MCP at different locations will have similar TOF results instead of varying widely (see figures below). Some of our standard products are listed below, and we welcome requests for customized MCP assemblies.
These electron multipliers feature a wide dynamic range, robust structure, lower price than MCP assemblies, and other beneficial characteristics. Our standard products are listed below, and we welcome requests for customized electron multipliers.

For magnetic sector mass spectrometers, we offer an electron multiplier in the shape of a thin rectangular plate. Several of these electron multipliers can be combined to simultaneously detect ions with different m/z values as they exit the magnetic sector mass analyzer. This ion detector has a wide dynamic range and robust structure. In addition to our standard product, we welcome requests for customized electron multipliers.
Flow cytometry is a technology that measures various physical properties of single particles, usually cells, as they flow in a stream of fluid through a laser beam. The characteristics that can be measured include a particle’s relative size, relative granularity or internal complexity, as well as fluorescence intensity. These properties are determined by using optoelectronic detectors, such as photodiodes, photomultiplier tubes (PMTs) or cameras. The detectors monitor how the cell or particle scatters incident laser light and emits fluorescence.
This technique is routinely used throughout the life- and biomedical sciences and can be applied in virtually any scenario where rapidly profiling large populations of cells or particles in a liquid media is necessary. Typical applications comprise of routine diagnostics in haematology, immunology or infectiology. In immunology for example, flow cytometry is used to identify, separate and characterize various immune cell subtypes by means of their size and morphology. This analysis plays an important role in the diagnosis, treatment and prevention of diseases.
