食品检测仪主要是用来检测、检验和分析食品中有毒、有害物质，现有的食品检测仪主要有以下几类：
Food detectors are mainly used to detect, inspect, and analyze toxic and harmful substances in food. The existing food detectors mainly include the following categories:
①农药残留检测仪器：主要是气相色谱仪(GC)加液相色谱仪(HPLC)辅助检测，当物质较为简单时，用气相色谱与质谱联用仪(GC–MS)定性检测，当基质较为复杂时，用 LC–MS 甚至用 GC–MS–MS 确证。
① Pesticide residue detection instruments: mainly assisted by gas chromatography (GC) and liquid chromatography (HPLC) for detection. When the substance is relatively simple, qualitative detection is performed using gas chromatography mass spectrometry (GC-MS). When the substrate is complex, LC-MS or even GC-MS-MS is used for confirmation.
②有害化合物残留、渔药和兽药残留检测仪器：由于这类残留物较复杂，一般用液相色谱仪进行检测为主，以气象色谱仪、离子色谱(IC)、薄层色谱(TLC)等辅助检测。当需要做多种残留快的速检验，几乎均用 LC–MS–MS。
② Detection instruments for harmful compound residues, fishery and veterinary drug residues: Due to the complexity of such residues, liquid chromatography is generally used as the main detection method, with auxiliary detection methods such as meteorological chromatography, ion chromatography (IC), thin layer chromatography (TLC), etc. When multiple rapid residue tests are required, almost all LC-MS-MS are used.
③有害元素及其价态的检测仪器：最常用的检测仪器是原子荧光光谱仪(AFS)、原子吸收光谱仪(AAS)、电感耦合等离子光谱仪(ICP)和具有更高灵敏度的 ICP–MS；为鉴定元素的价态，一般采用元素分析仪与各种色谱分离系统联用。
③ Detection instruments for harmful elements and their valence states: The most commonly used detection instruments are atomic fluorescence spectrometer (AFS), atomic absorption spectrometer (AAS), inductively coupled plasma spectrometer (ICP), and ICP-MS with higher sensitivity; To identify the valence states of elements, an element analyzer is generally used in conjunction with various chromatographic separation systems.
④细菌病源性检测仪器：传统的检地变电阻柜 精密铸造 中频电炉设备 保定断桥铝门窗 保定养老院 镜子批发 启闭机测仪器是用镜检和菌落计数器等，用于细菌、致病菌鉴定的仪器有六种以上。广为应用的仪器包括基因检测仪器、碳源代谢利用率检测仪器、生物芯片技术平台、基于表面等离子谐振(SPR)仪器及基于细菌特征脂肪酸谱的仪器。
④ Bacterial Pathogenic Testing Instruments: Traditional testing instruments use microscopy and colony counters, among others. There are more than six types of instruments used for identifying bacteria and pathogenic bacteria. Widely used instruments include gene detection instruments, carbon source metabolism utilization detection instruments, biochip technology platforms, surface plasmon resonance (SPR) based instruments, and instruments based on bacterial characteristic fatty acid profiles.
⑤微生物毒素检测仪器：使用较多的是酶标仪、薄层色谱仪、黄曲霉素测定仪等，内源毒素类可用液相色谱仪或分光光度计检测；近年来海洋生物毒素的检测广泛运用液相色谱仪以及 CE 和 CE–MS 联用仪检测。
⑤ Microbial toxin detection instruments: Enzyme-linked immunosorbent assay (ELISA), thin-layer chromatography (TLC), and aflatoxin analyzer are commonly used, while endogenous toxins can be detected by liquid chromatography or spectrophotometer; In recent years, the detection of marine biotoxins has been widely used using liquid chromatography and CE and CE MS coupled detection.
⑥转基因产品检测仪器：主要方法包括基因转录水平和基因水平的检测，主要使用离心机等制备基因样品的设备，用基因扩增仪(PCR)和酶标仪、电泳系统等进行分离、分析和检测的仪器。
⑥ Transgenic product testing instruments: The main methods include gene transcription level and gene level detection, mainly using equipment such as centrifuges to prepare gene samples, and instruments such as gene amplification machines (PCR), enzyme labeling machines, and electrophoresis systems for separation, analysis, and detection.
