实验室的安全运作，离不开对气体使用的严格把控。气体安全不仅是实验室人员安全作的基石，更是保障整个实验环境稳定运行的先决条件。不同供气方式的安全风险各有差异，

目前，氮气钢瓶在实验室中广泛应用，其潜在的危险性却不容忽视。不当操作、气体的易燃易爆性、泄露风险以及高压问题等，都可能导致安全事故的发生，给实验室带来不可估量的损失。因此，我们必须高度重视气体使用的安全性，确保实验室的平稳运行。

本文将带您了解实验室常用气体钢瓶的安全风险、可能造成的后果，及能够替代钢瓶并具有更高安全性的气体解决方案。

1、钢瓶使用、操作的安全风险

实验室中的气体钢瓶，尽管在科研工作中扮演着不可或缺的角色，但其安全风险亦不容忽视。在使用和操作这些钢瓶时，实验人员必须接受严格的安全培训，确保操作规范，减少受伤风险。然而，这往往费时又费力，成本高昂。

钢瓶在搬运过程中也潜藏着巨大的安全隐患。一旦不慎倒地，极易导致钢瓶内气体泄漏，而高压气体更可能使钢瓶瞬间化身为危险的“火箭筒”，给实验人员带来严重的生命威胁。

2、钢瓶泄漏风险

钢瓶泄漏风险更是让人触目惊心，不仅给实验室带来巨额的财产损失，更严重危害实验人员的人身安全。易燃易爆气体导致事故的新闻屡见不鲜：2023年8月13日晚，江苏连云港东海县一石英制品公司内发生氢气泄漏并引发火情；米兰南郊仓库里发生液氮泄漏事故；江苏某化工园区发生液氮泄露事故

氮气是一种惰性气体，但在密闭空间中释放的液氮气体可以迅速置换空气和肺中的氧气，导致人体失去知觉并发生致命的窒息。一旦实验室的氧气含量降低到18%以下，就有可能损害判断力和身体机能。氧气损耗程度对人体的影响可参照下表。

氮气发生器的气体解决方案

[/fusion_title][fusion_text animation_direction=”left” animation_speed=”0.3″ animation_delay=”0″ disable_idd=”no” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” sticky_display=”normal,sticky” fusion_font_variant_text_font=”400″ fusion_font_family_text_font=”Montserrat”]

使用氮气发生器替代钢瓶，能够完全避免以上多种风险，以及随之而来的高额损失和人身伤害。

 

• 安全可控

就莱奥氮气发生器而言，在实验室处于密闭环境状态，每台莱奥氮气发生器内部配置了安全功能，会在氢气泄漏之初就发出警报。

一旦您的实验室安装了莱奥氮气发生器，就不再需要移动。而钢瓶用完后需要反复更换，且在更换钢瓶时，分析实验的过程不得不停止，这对实验室工作人员来说操作繁琐，也存在安全隐患，同时也降低了实验室的工作效率。

• 按需供气

莱奥氮气发生器根据后端仪器当前所需的气体量按需产生气体，现场生成，即产即用，同时，只会储存少量气体，即使极端情况下发生泄漏，也不会导致爆炸或窒息风险。

NG-M35氮气发生器在8bar的压力下，流量为35 L/min，与气体钢瓶相比，大大消除了气体泄漏和高压带来的潜在风险。

• 可远距离供气

若实验室有多台质谱需要供气，多台氮气发生器想集中存放于单独一间房，莱奥氮气发生器输出压力最高可达10bar，且可长时间维持高压运行，满足客户远距离供气要求。

 

莱奥气体发生器为实验室提供了更安全、更精简的一站式气体解决方案，消除使用钢瓶可能带来的安全风险和高昂损失，同时简化实验人员的工作流程。
