Longpan

Longpan, also presented on its official website as 龙盘科技, is the commercial identity of Shaanxi Longpan Biotech Co., Ltd. The company describes itself as a technology-innovation-driven high-tech enterprise and a supplier of domestically developed scientific instruments. Its stated focus is research and sales of high-end scientific instruments, with particular attention to core technologies in chromatography and mass-spectrometry analysis. The product range shown on the company’s product page includes high-performance liquid chromatographs, gas chromatographs, mass spectrometers, combined analytical systems, and accessories and consumables. Named offerings include the LP01S series of liquid chromatographs, the LP02 series of gas chromatographs, the LP035500 portable GC-MS, the LP03800 GC-MS/MS, an HPMS-TQ triple-quadrupole LC-MS system, and the LP03MS8010 ICP-MS. The site also lists AlphaHybrid, Alphasil, Marsil, and StarCore chromatography columns, as well as SelectPrep sample-preparation consumables and media. The company identifies food, pharmaceuticals, environmental testing, disease control, clinical testing, customs and inspection/quarantine, petrochemicals, and scientific research as application areas. Its website presents the business as serving laboratory, research, and industrial analytical needs, and describes a production base equipped with automated production lines and laboratory testing equipment. It also states that the company has a research team of experts and engineers and holds invention and utility-model patents, without naming individual researchers or providing a verifiable detailed patent list in the supplied material. The company gives an address in Xi’an’s High-tech Zone, Shaanxi, and lists a service telephone number on its website. Its history page contains inconsistent founding references: the homepage and company profile identify 2017, while the history text also says it entered the scientific-instrument field in 2012 and includes conflicting, evidently unfinished timeline copy. Accordingly, a precise founding year cannot be established from the supplied evidence. The website displays a news section with dated notices and industry-related updates, but the evidence does not establish a corporate parent, owner, listing status, named executives, or sales figures that can be reliably attributed to the company.

The available official company material presents Longpan as the brand of Shaanxi Longpan Biotech Co., Ltd., a Xi’an-based scientific-instrument company. The company profile says it has operated since 2017 and describes the business as focused on research and sales of high-end scientific instruments. It says the company works on chromatography and mass-spectrometry analysis technologies and serves scientific research and industrial applications. The official history page does not provide a consistent chronology. One passage says the company began participating in the scientific-instrument industry in 2012 and describes subsequent years as a period of incubation. The same page labels a 2017–2019 period as brand strategy and says it began investing in the market in 2019. Other timeline text refers to 2019–2024 strategic layout and 2024–2025 customized research, but includes placeholder-like wording and conflicting claims. The homepage and company profile separately identify 2017 as the company’s establishment year. These sources do not establish whether 2012 refers to an earlier activity, predecessor, or something else, so the exact founding date and the sequence of corporate development remain unconfirmed. The company’s product catalogue documents a portfolio spanning liquid chromatography, gas chromatography, mass spectrometry, combined instruments, and consumables. Listed products include several LP01S liquid chromatography systems, LP02 gas chromatographs, a portable GC-MS, a GC-MS/MS system, a triple-quadrupole LC-MS system, and an ICP-MS instrument. The catalogue also names several chromatography-column product families and SelectPrep sample-preparation products. The company states that its products are used in food, pharmaceutical, environmental, disease-control, clinical-testing, inspection and quarantine, petrochemical, and research settings. The profile describes a research team of experts and engineers and a production base with automated production lines and laboratory testing equipment. It also claims to have obtained invention and utility-model patents, but the supplied pages do not identify the patents or provide independent verification. The company website currently presents its product catalogue, application areas, technical support, company information, contact details, and news. It gives a business address in Xi’an High-tech Zone and a customer-service telephone number. The available evidence does not identify founders, named executives, ownership or parent-company relationships, listing status, or a reliable corporate founding date.
