Hello Good evening.

Now we shall learn about Cuvette path length determination which is being used under UV-Spectrophotometric analysis. 

 


two side of the cuvette 
 2x 1.25     mm         

               12.5mm outer diameter of the cuvette 

 And the wall thickness

Here is how to calculate the

Cuvette path length:

(Wall Thickness x 2) – Outer

Dimension = Path Length

Let’s take Type 1UV10 as

Our  example.

Wall thickness: 1.25 mm

Outer Dimension: 12.5 mm

1.25 x 2 = 2.5 mm

12.5 – 2.5 = 10 mm

Many analyst forget to double the wall thickness so it’s essential 

 to make sure you do this. See above diagram  for a top view

of a 10 mm cuvette to see how we calculate the cuvette path

  Good evening all   This post is for the new trainee and 1-2 years experienced Pharma QC analysts, to understand about ppm level concentration solution preparation.  I will start sharing the analytical concepts with the very  basic level, to understand easily, so that you understand the concept and utilize in the routine analysis practice.  Kindly suggest me on which analytical topic you need the basic information.  Todays topic is ppm level solution preparation  ppm level  solution preparation  ppm = parts per million ppm is a term used in chemistry to denote a very, very low concentration of a solution. One gram in 1000 ml is 1000 ppm and one thousandth of a gram (0.001g) in 1000 ml is one ppm. Example-1   1gm in 1000mL is 1000ppm  let me explain  1g x 1000000(for converting in to ppm)            =  1000ppm             1000ppm =10...
