TDLS500(ICOS)分析仪，在恶劣的条件下也可以快速连续的测量。通常，工艺条件下的痕量级分析需要采用过程气相色谱技术。这种方法的缺点就是分析时间长，通常以分钟计算，因此无法提供连续测量。
离轴积分腔输出光谱技术采用高精细度光学腔作为吸收池。传统的多程排列的光通道长度通常局限在200m以内，与此不同的是，离轴积分腔输出光谱技术吸收池可以高效分离激光光子，从而在离开吸收池之前制造出成千上万的光通道。因此，采用高反射率的激光反射镜，光通道有效长度就可以增加至上千万米，而且，通过光学腔的待测光吸收量也大幅提高。比如，一个吸收池带两面反射率达99.99%的反射镜，镜间距率是25cm，则光通道有效长度可达到2500m。
由于光通道长度取决于光学腔的光学损失，而不是取决于独特的光束轨道(如传统的多程吸收池或腔体响铃系统)，光学校准非常可靠，可以满足现场稳定运行的需求。
同传统的波长可变吸收光谱技术一样，激光器的波长根据所选待测物的吸收特性进行调节。所测吸收光谱会记录下来，再结合吸收池的待测气温度和压力、光通道有效长度，和已知的谱线强度，确定浓度的定量测量。TruePeak测量方式通过积分求得吸光度面积，而不是仅测量峰值高度或峰值宽度。意味着分析不受干扰。至于响应速度，ICOS分析仪采用了第一原理测量，可以证明测量采用的是实时光谱亦或是历史光谱。
