On January 3, GLONGHUI (688056.SH) said during the survey of specific subjects that from a technical point of view, the triple quadrupole mass spectrometer (ICP-MS/MS) has a larger vacuum chamber than a single quadrupole mass spectrometer and requires professional engineers to design multi-stage vacuum gradients that match the triple quadrupole; moreover, in order to guarantee higher sensitivity and lower background, the company added an independently patented mass spectrometry interface and ion lens to effectively control background signals while obtaining higher sensitivity. At the same time, according to the customer's actual usage scenario, the company adjusted ion focus and transmission, constructed various operating modes and program frameworks, and independently developed flexible and simple control software to ensure stable signal transmission and fast data processing during ICP-MS/MS serial use. In terms of application fields, the triple quadrupole mass spectrometer currently released by the company is mainly aimed at semiconductor industry applications. Compared with single quadrupole mass spectrometers, it is mainly aimed at solving the needs of higher detection sensitivity, stronger anti-interference ability, and lower detection limits in the application field. The company's two mass spectrometers can meet different needs in terms of application according to the different testing requirements of customers, and the market sales prospects are broad.
