The sample target/target plate/channel plate is made of stainless steel plate, with a length, width, and depth of 3.0, 0.35, and 0.40 mm, respectively. Material: stainless steel channel size: 3.0 * 0.35 * 0.40mm. Keywords: sample target/target plate/channel plate. Product details: made of stainless steel plate, with a length, width, and depth of 3.0, 0.35, and 0.40 mm, respectively. It is a standard target plate that can be reused and directly applied to the sample target coating layer. It can be used to study 96 samples made of stainless steel plates at a time. The length, width, and depth of the channels are 3.0, 0.35, and 0.40 mm, respectively. The target plate surface has highly regular fine structures, which can achieve highly uniform eutectic preparation (dry drop method). The processing process uses a 3-axis+4-axis machining process to ensure flatness, while also ensuring the same process for side features, ensuring positional machine control. The scope of use: This target plate is used for medical detection, mass spectrometry, Q-Tof Premier MALDI, Q-Tof Ultima MALDI, and MALDI SYNAPT HDMS/MS System
