预制菜
预制菜是指经过预先加工、切割、烹饪或处理后的蔬菜、肉类、豆类等食材。这些食材通常被包装在一次性餐盒或袋子中，以供消费者直接烹饪或食用。简单来说，可市面上很多可即食、即热、即烹、即配送等方式的食物都属于预制菜。那么，预制菜已经在我们身边随处可见，食品安全问题，则需要对预制菜进行监管和抽检。
预制菜需要做哪些指标检测，需要哪些仪器？实验过程需要注意什么？莱奥一次性帮您梳理清楚！

2、检测过程部分步骤必须更换手套，避免交叉污染，苯并芘如已污染了皮肤，应采用 10% 次氯酸钠水溶液浸泡和洗刷，在紫外光下，观察皮肤上有无蓝紫色斑点，直到蓝色斑点消失为止。
3、如果用净化方法1，中性氧化铝柱需储存在避光干燥的环境中，否则空气中水分会影响中性氧化铝柱的性能，从而直接影响苯并芘的加标回收率。
4、固相萃取柱子不同厂家的质量差距较大，每次使用不同批次柱子前一定要做验收，合格了才进行检测。
5、样品过柱时候，速度需要控制1ml/min，速度不要过快或过慢，避免柱子干柱。

2、流速可控，回收率佳：过柱时候，速度需要控制1ml/min，Leowlab Purifier A48 48正压固相萃取仪可通过调节压力，准确控制流速。
3、批量大，效率高：样品量最大可兼容48批次，同时过柱及氮吹，节省实验时间。
4、固相兼容氮吹，无需转移：过柱后样品架可直接转移到Leowlab SmartVap AE 48位全自动氮吹浓缩仪，避免转移带来的损失。
5、涡旋斜吹技术：Leowlab SmartVap AE 48位全自动氮吹浓缩仪，采用斜吹技术，可更加快速，平和、防飞溅的基础上，很好的完成氮吹。
6、筛选氮吹针误差测试，保证平行性：Leowlab SmartVap AE 48位全自动氮吹浓缩仪的氮吹针经过针与针直接误差测试，层层筛选过，保证氮吹样品的平行性。
7、氮吹不跟随液面下降：Leowlab SmartVap AE 48位全自动氮吹浓缩仪不跟随液面下降，防止样品交叉污染。
