</p> <p> <br /> </p> <p> (1)非單色光的影響：紫外一可見分光光度訃使用連續(xù)光源和分光器分光，不可能得到真正理想的單色光；為保證在測(cè)量中能得到充分的光強(qiáng)，儀器必須保持一定的狹縫寬度。由狹縫射出后投射到被測(cè)物質(zhì)上的光，是一個(gè)有限寬度的譜帶——光譜通帶。隨光譜通帶寬度的增大，吸收光譜的分辨率降低，并偏離朗伯一比爾定律。 </p> <p> (2)非吸收光的影響：當(dāng)來自出射狹縫的光的光譜通帶寬度大于吸收光譜譜帶時(shí)，投射在被測(cè)物質(zhì)上的光就含有非吸收光。這不僅能使靈敏度降低，且能使校準(zhǔn)曲線向橫坐標(biāo)軸彎曲而偏離朗伯一比爾定律。石油紫外可見分光光度計(jì)代理紫外分光光度計(jì)（UV
