专家通常需要分析河流、海洋、地下水和其他水源的污染,以确定环境恶化的原因和潜在的健康危害。因此,环境监管机构需要一种可靠、高效的方法来使用法律规定的参考值和测量方法测量潜在的水污染物。
滨松为检测微量污染物成分的水质检测设备提供高灵敏度光传感器和高亮度光源。
溶解的有机分子通常在紫外 (UV) 波段表现出强吸收。该方法通过测量污染物对紫外光的吸光度来确定工业排水与河水中存在的有机污染物。
氮测量的一种方法是将溶解的氮转化为硝酸盐。紫外吸收光谱法(通常在 220 nm 处)是测量这些硝酸盐的强大技术。
测量溶解的磷可能具有挑战性。一种常见的技术是通过化学反应处理样品以产生钼蓝。880 nm 附近的吸收测量值可能与磷的浓度相关。
通过对工厂和容器排水照射紫外光并测量产生的荧光来测量油和多环芳烃 (PAH) 含量。
原子吸收特定波长的光,然后吸收的光以荧光的形式重新发射。原子荧光光谱测定是一种检测这种荧光并确定元素的分析方法。它可以高灵敏度测量 ppt(万亿分之一)级的汞等元素。
该分析方法通过热解离在雾化的样品上照射特定波长的光并测量吸收光谱来确定原子的数量。由于这种方法不易受到光谱干涉,因此可用于分析各个领域的元素(作为主要组分或痕量组分存在)。
这是一个高度稳定的光源模块,在紫外区域 (220/254 nm) 具有高亮度的特点。它被广泛用作紫外光吸收测量和荧光激发的光源,取代低压汞灯。它结构紧凑,由 5 V 电池驱动,因而可以安装在便携式分析仪器中。此外,还提供适合紧凑型分析仪器的圆柱形 OEM 型号。
C16767MA 是一款高灵敏度、超紧凑(指尖大小)的光谱仪探头。C16767MA 支持紫外区域(190 nm 至 440 nm)。该产品适合集成到各种紧凑型设备中。
这是一种硅光电二极管,带有专为 254 nm 光吸收测量设计的带通滤波器。灵敏度光谱带宽在 10 nm(典型值)处极窄,因此可以准确进行光度测量,而受杂散光的影响极小。此外,还有适用于其他波长的带通滤波器类型,例如 220 nm(用于氮测量)和 275 nm(用于参考)。
这是一种 TO-5 封装型硅光电二极管,适用于在 190 nm 至 1100 nm 波段具有灵敏度的吸光计。
除此产品外,还提供广泛的产品阵容,包括 TO-8、TO-18 和陶瓷封装,以及具有不同光谱响应范围的类型。
这是一款 CMOS 线阵图像传感器,灵敏度波段位于 200 nm 至 1000 nm 处,适用于吸光计。除此产品外,我们还提供广泛的产品线,包含不同的灵敏度、读出速度和其他参数。
这是一款薄型背照式 CCD 面阵图像传感器,灵敏度波段位于 200 nm 至 1000 nm 处,适用于吸光计。
除此产品外,我们还提供广泛的产品线,包含不同的灵敏度、读出速度和其他参数。
这是用于原子荧光计的 PMT。它对紫外光和日盲特性具有极高灵敏度。
这是用于原子吸光计的光电管,可用于汞监控。它对紫外光和日盲特性具有灵敏度。
