服务选择：多样化的选择
我们的植物信号分子检测针对植物的不同部位具有不同的选择，能够满足不同用户的需求：
（1）以平板电极为基底的电化学传感器
适用于扁平状、面积较大的植物部位的检测，如叶片等。这种传感器设计扁平，能够紧密贴合植物叶片，实现低损检测，进行高效的信号分子检测。
（2）以针状电极为基底的电化学传感器
针对植物根、茎等微小、脆弱部位，我们的针状电极传感器能够实现微损检测。这种传感器设计精细，对植物的损伤极小，同时保证了检测的准确性。
（3）以超微电极为基底的电化学传感器
对于需要更精细检测的用户，我们提供了微电极电化学传感器。这种传感器可用于检测植物细胞，如气孔微区等，为植物细胞层面的研究提供了强有力的工具。
竞品比较：优势满满、超值选择
目前多用气相色谱-质谱法(GC-MS)、液相色谱-质谱法(LC-MS)和高效液相色谱法(HPLC-MS/MS)等方法检测植物信号分子，但它们受到复杂和耗时的样品预处理步骤的限制，而且复杂的样品处理过程会导致植物信号分子受到损失。更此外，复杂的样品处理往往需要大量的植物样品，需要的时间也更长
而我们的服务能够实现原位、实时检测，操作简单便捷，出结果快，且价格适中。
