Mass spectrometry is an analytical technique that identifies and quantifies a substance by ionizing the atoms and molecules of the substance and measuring the mass number and number of ions. Compared to other analytical techniques, mass spectrometry gives a great deal of information in a single analysis and so can be applied to various fields including proteomics for studying proteins.
Hamamatsu Photonics offers a wide range of devices such as ion detectors that are indispensable for mass spectrometers.
A mass spectrometer mainly consists of an ionization section, an ion separation section, and a detection section. Mass spectrometers are grouped into various types according to the ionization and separation methods. The features required for devices in a mass spectrometer differ according to the type of the mass spectrometer. We have developed and produced a wide range of products related to mass spectrometry, such as ion detectors that are key devices for the detection section, light sources for photoionization, and measurement support tools for users. |

MCP(微通道板)是偵測在真空中的電子,離子,真空紫外光,X射線和γ射線,並放大檢測到的信號的二維傳感器。Hamamatsu 提供各種尺寸的圓形及方型的MCP(微通道板),包含易於安裝的MCP模組。這些MCP廣泛應用於許多類型的分析設備,如“質譜分析”,“半導體檢測”和“表面分析”。
MCP組件提供三種不同的讀取裝置,以滿足應用需求;分別為器件有:(1)單陽極(有效區域內的電輸出信號測量),(2)多節點(與信號輸入位置對應的電氣輸出信號測量)和(3)熒光屏(輸出信號的光學成像)。
Electron multiplier tubes are also called electron multipliers or ion multipliers, and are used to detect electrons, ions, charged particles, vacuum ultraviolet rays, and soft X-rays, etc. Electron multiplier tubes have high gain yet low dark current and are therefore useful for measuring very small particles and low amounts of energy.
Hamamatsu Photonics 電子倍增管也被稱為電子倍增器或離子倍增器,用於檢測電子,離子,帶電粒子,真空紫外線,軟X射線等。Hamamatsu Photonics 電子倍增管具有高增益及低的暗電流,因此對於測量非常小的顆粒及低能量非常有幫助。
DIUTHAME® ensures high reproducibility and accuracy in your mass spectrometry tasks!
DIUTHAME is …
… an ionization-assisting tool developed by Hamamatsu for MALDI TOF-MS (time-of-flight mass spectrometry). DIUTHAME streamlines the ionization process in mass spectrometry by replacing the matrix used in MALDI, and totally eliminates the cumbersome pretreatment of samples needed up till now.
