AB  - A device was designed integrating solid phase extraction (SPE) and in situ 
      optical detection techniques. A chip assembled in the device to carry out SPE was 
      enclosed in a fully reflective aluminum box to avoid loss of radiation flux in 
      the optical measurement. The spectrum was measured on the SPE material directly 
      after SPE. The device offers simple analytical operation without any elution step 
      comparing with the traditional analytical methods with complicated procedures. 
      The device and the developed analytical technique was used for the determination 
      of rhodamine B and benzo[a]pyrene with UV-visible diffuse reflectance and solid 
      phase fluorescence spectroscopies, respectively. Under optimal conditions, 
      standard curves of rhodamine B and benzo[a]pyrene showed a linear relationship in 
      concentration ranges of 10-800 mug L(-1) (R(2) = 0.99) and 0.07-3.33 mug L(-1) 
      (R(2) = 0.99), respectively. The limit of detections (LOD) were 7 mug L(-1) and 
      0.02 mug L(-1). The proposed device was successfully employed to quantify 
      rhodamine B and benzo[a]pyrene in tap water samples. The results showed that the 
      recoveries were 90-105% and the relative standard deviations (RSDs) were 
      2.53-5.55%, indicating that the device and analytical method is capable of trace 
      analytes for rapid quantitative analysis in various samples.
