Cary 630 Red or Low Energy

Question

Good Morning, 
 Would you please advise what are the possible causes of getting a low energy value of 16 on my cary 630?

Hi, 
 I am sorry no one has answered you earlier. In general, red energy indicates that amount of IR energy getting to the detector is either too high or too low. The normal value is between 15,000 and 28,000. In your case, the value is very low. I will list a few common reasons for that below: 
 1. Some sample that is left behind is absorbing too much. Please check you sample accessory to make sure it is clean. 
 2. The gain setting is incorrect. Please click the gain adjust button and try increasing or decreasing the gain to see if it will help. Please be careful of any method gain settings that can override the default gain value. 
 3. The source has failed. If the source is red, then it has failed. Please reach out to your technical support team to get advice. 
 If the above is not helpful, please reach out to your technical support team for assistance. Please see Contact Us | Agilent for details.
