Dont waste your time designing and/or packaging  a nano-amp input OpAmp circuit for your application.
Utilize one of our self contained  Ultra-low input modules  or  simply use in conjunction with a basic

Multimeter as an inexpensive alternative to an expensive precision ammeter. 

  CTVM08NF Gain:  
10.0nA/Volt  to  1.0uA/Volt 
  CTVS08NF Gain:   10.0nA/Volt  

   Gain Control (one of the following; option#1 is default):
             Option#1.) Manual 20 turn Trim-pot for Min. Gain to Max. Gain, respectfully. 
              Option#2.) Digital; Min. Gain, Interim Gain & Max. Gain selectable. 
              ( The above does not apply to fixed gain modules ) 

  Output Voltage:
Accuracy:  Better than 0.1%  ( 0C  to  50C )
Operating Temp Range:  better than   -10C  to  70C 
Enable / Disable Low-pass filter ( 15Hz ). 
  Enable / Disable High-pass filter ( 500Hz ). 
Offset Voltage Null Capability 
No Frequency Compensation Required 
Short Circuit Protection 
Low Power Consumption 
  Call for single supply/polarity, PCB only, custom
       application specific or small scale product alternative
